Need to vent. Any help is welcome.

So I have found myself in a pretty tough situation. Here is the deal, from the beginning. This mostly started when my doctor took me off my anti-depressant (Paxil 40mg) and started me on another SSRI. His reasoning for doing so was because of my weight gain. I might have gained 5lbs in a one year period. After going through withdrawals and taking this for over 2 months with no improvements, he put me on another drug, Viibryd. Well, this new drug, which he gave me a sample pack gave me some pretty serious side effects. The worst of which was extreme insomnia and episodes of mania. I would start to lash out at my significant other out of extreme anger. I haven't acted this way since I started my mental health treatment. But before, I would immediately feel guilt and remorse for my words or actions. On this medication, I felt nothing. I knew I was wrong but did not care. After this I decided to no longer take the medication. I still had a refill left on my Paxil, so I got that filled, and stared taking that. The insomnia has gotten better and the mania is gone.
But here is where my real problem is:
Before stopping Viibryd, I got into an argument with my immediate supervisor at work. He was treating another employee very badly, and I did not approve of his actions or words. As the Team Leader, working directly under this man, I felt it was my responsibility to step in and end the situation. He then turned and started yelling at me. However, my anger got the best of me, and instead of staying and arguing, I walked out of the job. I'm sure it wasn't the best way to handle the situation, but at the time, in the heat of the moment, it was either leave or stay and make things much more worse.
This may seem mean, but is truthful about my 'supervisor': He is a lazy, stupid man with no concern for the rules and standards of the company. The only reason he holds his position is because he is the brother-in-law of the owner.
I was promised by the VP of the company in the past (approximately 3 months ago) that I would be promoted over my current supervisor because I had proven on multiple occasions that I can not only do the job, but do the job more effectively and efficiently than he could ever do.
However, since I walked out of work (and was told by the supervisor not to come back) I'm not entirely sure that I will be able to get my job back.
I was a hard working, dedicated employee and my rapid promotion showed that. I have tried to contact the VP to set up a meeting with him to try to resolve the situation and so that I can get back to work, but have been unsuccessful in having any real conversation with him. I desperately need this job, as there is a very low chance that I could find another job that would match my pay and provide opportunities for advancement like I have here. Not only that, I actually enjoy this job for the most part. I have had other jobs where I dreded getting up every day and going in, but never felt that way about this company.
As bad as I need this job, tho, I want to demand that I get the promotion I was promised because I feel that I can no longer work for this man. I disagree with nearly all of his actions in the workplace. Even all the employees agree that we would all be better off with me running the show. I plan on showing up Monday morning when the VP arrives at the company to hopefully resolve this issue. But I'm not sure I have the right to demand my promotion after my unprofessional exit. Do I mention the problems I was having with my medications or not? Or do I just eat a big piece of humble pie and beg for my job back? Seriously lost/confused/scared/anxious of this situation. Someone please help me be prepared for this confrontation that I feel must take place.

Hi, jwork87, and welcome to Psych Central! Wow, that's a tough one. As you said, the guy you offended is a relative--and then you quit. I fear that will make any promises to you null and void.

You could beg for your job back and tell about your meds, but I am not sure that will help. Do they even know you have a historic problem with depression? I certainly wouldn't demand anything of anyone.

You might talk about how much you like working for the company and that you were having a temporary family issue that's now been resolved. (lie? well?) And ask for a chance to redeem yourself by them allowing you to work for awhile--say for five months?-- to show them it was a fluke. They would have to go through some effort to replace you anyway. Then maybe after that period of time things will have cooled off some, and you will get your job back on a permanent basis.

I suspect that's the best you might hope for. My thoughts, anyway.

Other folks? What do you think?

I sure hope everything will work out well. We are here for you, and we care.

I would not demand anything. Humble is the best approach. And hopefully with the VP you can resolve it. At first I voted no on the telling medication question but after reading your post I am not so sure. Lots of medications for different conditions have bizzare side effects so you could possibly just not mention mental health and say it was a medication issue. In this day and age I am not even against lying when it comes to mental health in a work situation. Although i have found being open has been better for me but it is a sticky situation and I would lie if I thought I needed to. Like thyroid being out of whack would explain the behaviour.

Either way I think you will get your job back if you are humble and just own your part of it.

Yes, I debated about the med issue. I just worry that if you are vague about what the med was for, then they might force the issue and use (illegally, I would think) a history of depression as an excuse not to hire you back.

Please let us know how things go, either way. We care!
