I was in the same position at one point. Very similar to be honest with you except I didn't have the option of maybe staying with my parents, I had a move out date and that was final.

I felt like I was thrown to the wolves a bit because of my MH issues but I am now far better for it.

I won't lie to you, it wasn't an easy start either. It took me months to square myself off and get things in better order but I have grown from the experience and eventually learned to stand tall on my own two feet.

Sometimes we don't see how strong we can be until we are forced to be strong.

Good luck OP, just know that you will make it no matter what.
