I understand how you feel. I went to school for many years and really busted my *** to get my bachelors degree then my MBA then my CPA all while raising a child and working full time. I had to file for disability around your age and it really hit me hard. What a waste of time, money and effort! What a blow to my pride and self esteem! I also wondered if the stress I put myself through to obtain my education and my career caused the bipolar to become out of control.
I'm sorry you are feeling the way you are. I felt the same way. I still do some days and start thinking about going back to work but I know, in reality, I'm not ready. Disability is there for cases like ours. Good luck with the disability process.
