Reading this story was like reading mine (in most ways, that is...)
I'm 26, so slightly older, and I went through the inability to drive (at random, I already had my license and had been driving), and growing up I had times of refusing to do my homework, being bored in school, so goofing off...I was smart enough to keep my grades up to appease the 'rents (and so I didnt get yelled at)
I was diagnosed with depression, disthymia, borderline personality disorder, etc. I feel like I was misdiagnosed now because treatment for those disorders NEVER WORKED.
I am also uninsured so treatment and diagnosis are difficult. The University I attend has a student health center, but, being that adhd medications are abusable, especially by college students, they have screening tests, but no diagnostic tests, and a referral to a psych will just take forever and my grades are falling (legitimately. Ive never studied before, Ive been able to BS my way through everything until now), and my anxiety is going through the roof.
I hope things get better for you. Living with the weird headspace is a challenge and can be awful. Good luck
