I get anxiety all the time. I'm 22 years old already. Only had one serious relationship and it ended a year ago. I'm the best looking guy and I'm not exactly and overachiever. I Feel like the time is ticking and if I don't find someone in the next year or two it will most likely never happen. Don't want to be that weird uncle.
You dont have to rush into love. It will come when its ready to be in your life. People dont meet their life partners till they are in their thirties or older. Dont stress it, have fun while you can.
I feel like I would be forever alone but only in the stereotypical way as in I would not get married or be with one person 'forever' but maybe have different relationships or experiences throughout my life which I dont mind. But I do feel a pressure to be with one person because that is the safe usual life. You do not need to be worried! You're so young you have so much time you should be having fun and you shouldn't be worrying about this at all! :) you will find someone in time if that is what you want ;)
