Truth is you have to get yourself out there and give yourself the opportunity to meet people who end up truly caring and fit you well. Even if that means you will make some bad experiences on your path its the only way to find what you need.
Chances are you are either stuck in a rut without motivation and drive to change things (potentially depression) or you are scared/have anxiety of what could go wrong or the unknown in general. Maybe youre just used to only do things you feel like doing instead of doing things you wouldnt naturally gravitate to without a specific goal in mind. All of these things are understandable and not something to be ashamed of.
One of the biggest lesson you can learn is that good things in life dont always just fall into your lap as you live through the same daily cycle. Sometimes it requires Initiative . You have to do something to get yourself towards a better life. Often times it feels much scarier than it needs to. Try to get yourself into situations where people are present with the goal of socializing . Preferably something where you can bond over shared interests to make the start easier. Be nice, dont be scared and be yourself.
And since it sounds like you might still be in school: Every time your life goes through a major shift (e.g. going to uni, getting a new job, moving cities) you get a new easy shot of running into something good.
Dont expect to strike gold immediately and get disheartened if it doesnt work. I mean it could easily happen but its no guarantee. It is a new way of living and thinking you need to adapt that bears fruit longterm.
You may get some "no"s, you wont mesh well with everybody and some of the things you do wont end up being a good time but that is okay. If you dont play you cant win and "losing" is often nothing more than a day you will forget some weeks later.
I can guarantee you that there are many people that would care about you a lot and you would likewise but you are hidden from them hard to be seen.
Edit: Some of this is guesswork. I obviously dont know much about your situation and other factors at play i might be missing but i wanted to pass on some of the lessons i learned on my path and i hope it is at least of some value to you.
