I recently entered a program that helps adolescents and young adults with figuring out their careers/getting job experience, it starts the first week of June. The program only happens for the summer, so if I wanted to do it again I'd have to wait next year.

My problem is that I'm extremely suicidal and actively self harming, being admitted would be a safe thing as I don't trust myself at all. 
When I'm admitted I typically stay for 14-20 days, but it's only that short because I cannot handle poor living conditions and it makes my mental health worse--I had to lie and pretend I was better to be able to leave quicker because the hospital was disgusting and the staff didn't give a single fuck about the patients.

I'm SUPPOSED to be going to a partial inpatient program that focuses on DBT but these hospitals are incredibly fucking inept and it has taken them over 3 weeks just to get information from my last physical. I don't know what's going on and they won't inform me, I can't even talk to my therapist about it because she's probably sick and hasn't contacted me at all since the 16th

I don't know what to do at all and everything is overwhelming. I have no friends I can rely on and my family has no patience with me anymore. At this point I want to give up completely and just let myself get worse and continue to self harm until I decide on a suicide method that isn't ridiculously embarrassing. I don't know if I should just suck everything up and do the summer job thing or go to a psychiatric hospital.
