I really wish I could use the "I'm Bipolar" excuse as well, but many people don't understand what Bipolar is, and how it's an actual medical condition in which you can't always control. Maybe you could look into support groups in your area. The DBSA (Depression & Bipolar Support Alliance) usually have weekly meetings, that are peer-lead. You can also maybe ask others without insurance what they do in terms of being treated. As for the SAD symptoms, have you tried light therapy? I got a LED light therapy thing on Amazon that I use for 30 mins in the morning, and it makes such a difference. I also take vitamin D supplements, folic acid, and NAC, with my psych drugs to make them more effective.

You should also try talking to your boss and see if there are things at work that can be changed that can benefit you. Luckily, I have an understanding boss, that helps me work out things when I'm having problems. For example, I also have ADD, so every morning she checks in on me to make sure I have my priorities right for the day. Also, she controls all of the tasks that I need to accomplish, unlike before when everyone was asking me for stuff, which was very overwhelming....I'm actually much more productive now.
