Homeless again

I had a great 5 yrs till I moved back home (5 hours away) to help take care of a family member that is declining in health. My family never gets along with me I’m unsure why I felt like I needed to be the bigger person, why I felt that this will be different.
Fast foward…
Im now homeless because I ended my life to help others, I have no money cuz I was living off my savings however I manage to have a “friend” who is lending their sofa/couch till the end of the month. Idk how imma eat, how imma get my medications, how imma stay sober and how imma stay alive.
