My first girlfriend broke up with me

So I am 22 and I was always an outcast, got my first official relationship around 20 with her. And it was because of both our mothers noticed we were eyeing each other and got us to date and weve been happy ever since

Or so I thought we couldn’t see each other on Christmas day so we texted. Last thing she texted me was “I love you so much❤️” and 2 days later “We need to talk”

She told me she breaks up with me because its an useless relationship and she brought up fights over 1 year old (i was jealous and broken a few promises, but I thought we were good now) so now Im still in shock

I got out of my bedroom around 13:00 today, sitting in just crying, takes all my willpower not to text her or call her crying to take me back… and in these 2 years we did anything together so not only do I feel like I have no gf, I feel like I have no friends too… my best friend is in another country I could try texting him tell him how I feel he has more experience me but I’m worried what he’ll think of me, I’m worried what my parents will think or her parents. So far nobody knows yet. I just feel so sad and its hard for me to even brush my teeth.

I also feel like there are no other girls who will ever date me because of my social awkwardness, she was a bit like me but better at social interactions, I feel like I have I’ll be alone forever
