Just letting it all out, some kind advice or just symapthy will be good

I'm the kind of person who struggles in communication especially when I have to initiate it. There is this constant thought of being judged or saying something that the other person won't like or might get hurt.

I don't go out much so there is also this fear of being left out. I feel like I don't have much opinion even for small things such as what to eat, where to go etc etc. It can be said that I'm totally in my comfort zone and horribly afraid to get out of it.

I've completed my college in my city and never even attempted for a job cause that seemed too much of a burden to me.

Once I was out with a bunch of friends of one of my friends and they all were strangers to me, when they asked to introduce myself I didn't know what to say, when one of them asked me about my hobbies, it seemed that I don't have any hobbies other than watching movies/series and a lil bit of painting which even a 2 year old can do. At that time I felt very inferior, inadequate, outpaced, whatever you want to call it.

I always feel like I'm not good enough and these all things shake my self confidence as hell. I have the lowest self confidence one can imagine. I feel like I'm caught in a shell. Overthinking every little thing and idk how to get out of this shell.

Also I'm a people pleaser person and I don't know how to say no to certain things without being rude.

I have never shared any of these with anyone. So this is a bit hard for me. Even sharing this here, I'm having fear of being judged.

I hope I'm not alone in feeling all these.

Some kind advice would be really helpful.
