I completely agree with Jaq!
I have a degree, a husband, 3 children and 3 dogs. I'm not working, I do this voluntarily and am about to start training for another volunteer role. I won't be able to teach again realistically due to my illnesses, and that sucks as I adore teaching, but I have to do what I can and where I can. It doesn't make me stupid or any less valuable in society at all because of it. You need to find a way to changing your thought processes.
I'll also add that some of the meds I take daily are horrible and I hate them, but I hate them less than I hate life without them. Sometimes you have to take the meds to help..... or counselling or psych or call a helpline or the crisis line - there are so many options, you just need to take them.
