Anyone got any advice on getting out there socially and to become acustomed to the world and stuff?

Hi there everybody, I'm Cooper802Forever and I'm an introvert, I have major anxiety when it comes to getting myself out there, weather it's getting a job, going out, living life, or making friends. So I wanna start getting my life together and attempting to be more out there, but I'm very anxious and scared, I don't usually go out and socialize with many people at all, and I feel like I need to somehow become accustomed to being in the presence of people, and just the enviroment. And its been hard on me because i don't do anything about it, i myself and others have been wanting me to get a job and go out more, but im just extremely scared and anxious. This is why ive started feeling this pain in my heart because i myself feel like I'm hopeless and that I'm a nuisance or a burden and it hurts.

And I was wondering if there'd be anything I could do to dip my toes into that somesort of atmosphere where I can be accustomed to seeing people, or anything you think I could do to better myself when it comes to this.

Cause I was actually thinking maybe going to the gym would provide me with a sort of atmosphere of seeing people everyday, and just focusing on myself. Does this seem like a good idea? Please give me your advice/opinions on the matter because I want to get over this and get out there! 🙂
