As a neurodivergent dude growing up emotionally neglected (with cptsd because of that), I only started living after I left home.

My advice, and that was really hard for me - start trusting people. Not blindly, but at least try. Also, ask for help. You will be surprised by the amount of people that actually say yes.

Oh, later edit - learn to cook. Basic stuff at first, but that will help with your diet, your budget, impressing some so…
