Job, meds, medical treatment (for example TMS), find an apartment to live on your own. You probably heard it a million times so sorry for saying it once more. Im in similar shit as you so i can't really say anything enlightening, just the regular advice. If you are looking for suicide advice i can only tell you what not do. Don't try to overdose on meds (almost never works). From personal expirience hanging is excrutiating so i don't recomend it. Maybe decapitation by train or pottassium chloride intravenously (MIGHT) work. If you in the future have access to online shopping you could buy SN, 1,4-Butanediol or something similar. Best wishes brother/sister.
