What do you do when you never had confidence when you were young and still don't have confidence as an adult?

My confidence kind of different from young to adult when younger I was more confident at talking I was very good at communication but scared going places by myself I was ok with relationships I would be in one but had to take tablets when younger for my nerves now I have learnt to go places by Myself doing more by myself but I don’t know I find hard to talk sometimes not all time but most my confidence slightly different in a way but not how should be compared to most still learning myself
