Everything feels overwhelming *TW*

Basically, I can't afford treatment and I can't go on like this.
I'm a 23 year old college student and I almost failed last semester. I ended up taking two incompletes, but I'm so debilitatingly depressed that I can't write a paper. I'm afraid I'll still fail one of these classes.

I also don't know how I can possibly handle this upcoming semester. All three of my best friends are studying abroad, so I'll be relatively alone. I also attempted suicide last semester, so I can't see how it can get worse.
I told my mom that I needed help and she wasn't too helpful. She always tells me to go to a general doctor and get on an SSRI, but I tell her I can't. I think she totally doesn't accept that I have bipolar.
She referred to my hospitalization as my "little mental break" and never brings my mental health up.
Although, apparently I drunk dialed her and left a message sobbing where I repeatedly asked my friend if he hates me. The next day she texted me about taking a semester off.

I don't want to take a semester off, I have nobody to sublease my apartment to, and I have a job lined up when I get back to school. I also don't see how that would be helpful when she won't even help me get insurance or treatment.

I feel really bad. I need help so badly because I'm going to fail my classes, but I have no idea what to tell her. I already poured my heart out to her in a personal essay where I basically defended my diagnosis to her.

Any insight into what I should say? I have to get her to understand that I need help.

I would suggest talking to a psychiatrist and having them write a letter if necessary to get a medical withdrawal from classes. They can write a letter to your mom too. Your mental health is more important than one semester. I'd focus on getting on the right medication and therapy if needed.
