Hey dude
I am on your same boat but I enjoy my solitude
What I can recommend is opening a bit, at least a tid bit and see where it takes you, yes, you may get rejected by some people but someone out there will accept you as you are.
If you are more comfortable with online interactions and you find them as fulfilling as interactions in real life you could try slowly
Slowly is a penpal app that lets you connect with other people from around the world by exchanging letters
It has worked for me so far...
You can also use a webpage called meetup where you can browse meetings of people with your same interests
All in all, I know it sucks to be alone... please don't take this as me being judgmental because I am not being judgmental or telling you how to live your life
I am offering advice as someone who has been in very similar situations as yours, believ me I have been there and have felt that crushing desperation of loneliness and I have felt that crushing desperation of feeling... well... not liked
I grew up relentlessly bullied and mocked all my life by everyone who ever was in my life
With that said dude, please, try to find your inner love
That has helped me A LOT in overcoming all these situations that my silly little brain puts me in, I am little by little and VERY RECENTLY learned to tell my brain to shut it
When a negative thought comes I just try and turn it around and it has been helping so far
Once you find your inner worth and your inner love, things will come to you naturally it has worked for me lately, so I can tell you from experience that learning to love yourself helps
Where to start? Well do a small act of self love, as small as it may be dude, it can be just eating your favorite candy bar and telling yourself: "This is to me from me because I love me"
I know it's hard to say but say it even if it feels like a lie, lie to yourself and little by little you'll start believing.
Again i've been there dude, i've felt that, I know how it is to be completely alone and isolated from the world because you're different, I know how it is to wear a mask EVERY SINGLE DAY to be liked by people by fear of rejection... just... please try this little thing and see if it works
If it doesn't it doesn't mean that you will never love yourself dude, you just need to find something that works for you
only you can save yourself dude
I wish you success in your journey if you decide to start it, it's up to you in the end dude...
i don't wish luck because luck is random and sucess is a sure shot
keep shining, star
