College is making me manic again

So last year at this time I dropped out of college completely due to mental health issues. I’ve been dx bi polar since my early teens. I skipped spring and summer semesters and went back this fall.

But here we are yet again in my third manic episode of the semester. And I’m only taking three classes! Yes I can easily identify when I’m manic I’ve done this since I was a child and learned how to identify it when I was about 17. Idk what to do. I only have 8 classes left and my plan is was to graduate in fall of 2020. I just don’t want to disappoint my parents but I don’t know if I can do this. I can’t keep doing this for another year. This cycle of mania is horrible I don’t sleep, I stay up either watching whole seasons on Netflix or doing umpteen amounts of studying but yet retain none of the information like I’m reading and it just doesn’t stick. I am broke so I’m not going to therapy anymore. I had to get off of medical marijuana. I stopped seeing my cardiologist and taking those meds because I can’t afford those either. I’m just rambling now but I’m so tired of being manic. I woke up this morning and had sex with my fiancé even though I was already late for work. I never do things like that I’m always a good employee and never just throw my time away like that. I just don’t know what to do or how to tell my parents that I can’t even finish 8 classes.
