Reading your post made me remember my first depressive episode in my mid-20s and how awful it made my work.

If this is something persistent that you're dealing with, I'd encourage you to see if you can get some time off. Vacation time, whatever. (I don't know what sort of job you have - salaried, hourly, etc.)

Even if you can't get time off, the plan is sort of the same. I would make an appt. with a primary care doctor to talk about what's going on with you. Finding a therapist is the next thing to do.

Trying to keep my job was a big reason that I started taking psych meds. Ideally, we'd be able to take time away from work to educate ourselves about what's going on and to learn about depression and anxiety and ways to cope. Specific foods, exercise, relaxation, massage...there are lots of things that can help. It takes time to learn all this stuff.

Most of us don't have the financial cushion to be able to stop working while we learn this stuff, though, so we have to try to educate ourselves about it and seek help while continuing to work.

I also don't know what kind of workplace environment you have. In some workplaces, you can say to a few coworkers or your boss "I've started having some problems with anxiety. I may be acting differently than you're used to." and "I've made an appt. with a doctor to try to find out what's going on."

In other workplaces, that could get you fired or bullied.

Seeing the primary care doctor is important. There can be primarily medical causes that can trigger anxiety and/or depression like thyroid problems, anemia, and blood sugar issues. If it's not something like that, a primary care doctor can prescribe basic psych medication for anxiety or depression.

I'm glad you've posted here. These forums are a good place to get info. and also a safe place to express your frustrations and worries about what's going on.
