Struggling 😔

hey all. I've been in a relationship for two years. I'm 19 years old andin college. We got together our senior year of high school. We instantly clicked and he became my best friend. We were so similar and had faced so many of the same traumas, we both felt like we had met our soulmate. We were born a day apart and it felt like we were meant for each other lol.

fast forward to now. I'd always had difficulty with anxiety. In the past year, it has gotten so much worse. I have really low self esteem and tons of insecurities. Exactly a week ago, it peaked and I had a bad episode where I told him I wanted to break up. I wasn't in my right mind. We had gone through this before but he'd always bring me back down to rationality and we'd communicate and stay together.
This time, we didn't stay together. He told me he felt like we needed this. He told me he had some resentment towards me because he felt like no matter what, I couldn't be happy and he could never satisfy me. This hurt me especially because he never told me this, and I thought he was okay but he really wasn't. He told me he needed some space before we could come back together and try again.

I feel so alone. In the last year, I got rid of all my friends because we weren't really friends anymore and didn't have much in common anymore. He's my best friend and my only friend at the moment. He's the only person i'm 100% comfortable around. I love him to death.
A couple days after that, I also found out i'm pregnant.
