I tried to be a dad for a year with my ex-fiancé. Now it’s over and I don’t know what to do

I’m a 19 year old male with type 1 diabetes, I can’t go back home because then I won’t have insurance and I won’t be able to get insulin. I don’t want to stay here and live with my fiancé because now I feel like a fucking let down and mooch and she’ll eventually bring another guy over and I’ll loose my mind.

It all happened today, she told me she didn’t think I could handle it anymore and all I did was break down and cry in her arms. Now I have no where to go, no where to run,no one else to help me.

I’m fucked, I’m so fucked and I don’t know what to do.
