Hi!
I don't like public areas either! I think you are smart to avoid them whenever it's possible; especially these days. There are weird people out there and you never are sure where they may be. My husband and I avoid public events for that reason. Plus the increase in crime everywhere.
It sounds like you've been through a lot but are a survivor and are managing well. It's nice that your son lives with you. You can understand what he's going through. You are right. Things do always get better. Just keep praying. I'll say one for the both of you.
