How to socialize, how to get out

I have always been an introvert, My comfort is myself. I love my friends whenever I go out with them, and I never regret it. But I hardly go out. My social battery runs low if I do, around certain people too. The idea of unexpected things scares me and my anxiety now plays a huge role in me getting out and about.

I have fanacial anxiety about how much you actually have to spend when going out, I feel self conscious about my clothes, I fear what could happen.

Lately I find myself discouraged finding jobs because it feels like something scary since I haven't had one in awhile and that I feel discouraged because of my autism. It would mess with my routine, but also my routine is not healthy because all I do is stay inside and that makes me sad too.

How do I get out of this unhealthy routine, and create a new one where I can still be introvert but be happy to go out and have a life outside of my house
