Tips?

Tips? Any tips on how to cope with this? I’m 22 year old guy I’ve been isolating myself for about 4 years I have no friends or social help anyways today I somehow gained the courage to talk to a girl I liked and her and friends all just starting laughing super hard when I stuttered i just walked away and cried it felt like I could have died right there. I just hate how people hate or judge me off of something I can’t control and it’s been taking a toll badly on my mental health because it seems like everybody views me differently like some kind of joke. Any tips or ideas on how to cope and get rid of bad thoughts about this. Thank you for taking time to read this ❤️
