It's been such a long time, that I have no clue where to put this. :/ I apologize in advance if this is the wrong place!

I strongly believe I have been struggling with some mood disorder coupled with ADHD for awhile now. It only "recently" (7 years ago) started wreaking havoc on my academic and personal life. I have tried reaching out to my parents before. They took me to a hypnotherapist for awhile, but I told them it wasn't working. I had to practically nag them to let me see a psychotherapist, and I only had one session with her. My mother claims I said I didn't want to go back (and then never bothered to reschedule when I said I wanted to), and my father simply said "You can't expect a therapist to solve your problems" on the car ride back from my first session. Really, what put them off is the fact that the psychotherapist wanted me to see a psychiatrist. She made it very clear that she just wanted a clinical diagnosis and I didn't have to start medications, but I guess that wasn't enough for them. Anyway, from what she gathered at our first session, she suspected ADHD and/or a mood disorder as well. My GP suspected dysthymia, but I wasn't entirely honest with my symptoms because my parents were in the same room and my GP sent in an attractive medical intern to write down my symptoms and medical history (I know, that was stupid of me!) My GP also said it was normal for teens to have thoughts of suicidal ideation, and really not of any concern unless I made a plan to kill myself. So...um...I wouldn't exactly say he's the go-to expert on mental illnesses!

The thing is, I'm 17 now. I'm graduating early from high school in the coming weeks (homeschooled). I'm starting college soon. I'm barely passing school, because I keep going through periods of sadness and apathy that prevents me from doing schoolwork. And of course when I'm "normal" again, I can barely focus on anything. I absolutely cannot get away with this in college and expect to pass. How do I convince my parents yet again that maybe I need to get some help for this? I need them to drive me, because I would have no other way to get to my sessions. I don't have a license because I lose focus when driving. I do well for a few minutes, but then I find myself zoning out and daydreaming after awhile. Nothing serious has happened, but it frightens me when I notice it. I'm sick of being a space-case. I don't want to make a complete idiot of myself when college rolls around.

Sorry this is really disjointed. It's pretty late here. Anyway, you guys have always been so helpful to me. I just wish I could be as helpful, lol.
