Wow, you do have a lot to deal with. I suffered from severe depression when I was in my early 20s, long before fibro entered my life. I remember what a struggle it was just to deal with everyday life. I was a single mother, too, and my inability to provide for myself and my son in spite of my education was incredibly frustrating, and only added to my depression. The fact that the economy was just as crappy as it is now didn't help. I was getting hate mail from the student loan people on a daily basis, and couldn't stand to even pick up my mail or answer the phone.
Then a miracle happened. A piece of mail was delivered to my parent's house. I thought it was junk mail, and went to throw it away. My mom yelled (well, not exactly "yelled") at me to open it, because ignoring it wouldn't do any good. Lo and behold, it was an invitation to an interview for a job WITH BENEFITS!!! I said, "this is a mistake, I applied for this three years ago." My mom said, "No need to point that out to them, just go."
And I did. And now I've been with the same employer for 18 years. My income has increased 700% over the years, thanks to promotions and longevity.
The Depression Monster still nips at my heels. Time has taught me a number of ways of dealing with that Monster. The fibromyalgia doesn't depress me, it makes me angry. I deal with the fibro fog (comprehension and memory issues) by programming EVERYTHING into my smart phone, and setting alarms and reminders.
What I'm getting at is that you WILL feel better at some point; you WILL find your "sea legs;" you WILL learn to cope with your bipolar AND the fibro; and you DEFINITELY have the potential to lead a very happy, fulfilling life in spite of the obstacles that have been placed in your path.
