I've felt like this for awhile, doesn't help that I have a very high-pitched child like voice. Honestly, the best thing you can do is to not pretend to be someone that you're not. You're not going to be popular so don't waste your time with that, focus on your studies and on doing things you like.
If you still want to have some social interaction your best chance is to get good at something normies are typically bad at. For me this was tech, you'd be shocked at how clueless normies are when it comes to the most basic tech shit. If you're experienced in something like that it will atleast give you something people will know you for and potentially ask for help with, this is honestly the only way I've been able to form connections with people.
Make yourself useful and reliable to people, it's one of the few things normies will appreciate
