Resentment in LDR

My boyfriend and I have been together for 2.5 years and he had to move out of state to pursue his dream of going to law school. We decided to do long distance, but I’m struggling with it immensely.

He is really happy out there and making a lot of new friends and goes out frequently with them. I’m so happy for him because this is so refreshing and important for him, but I cannot help feeling a little resentful. I feel left behind and lame (for lack of a better term lol) because I’m back in my hometown, living with my parents, and I don’t have as much of a social life. He was my best friend and him leaving has devastated me and made me more of a recluse than I even was before. It’s hard for me to be completely happy for him when In my head, im just mad at him for leaving me behind and being so happy without me while I’m miserable.

I’m trying to do things to fill my life, but it’s so hard sometimes with how depressed I feel. I just miss him. I just want him back.

I know he loves me and misses me, he reminds me of that, but it’s hard to not tell myself that I miss him so much more, etc.

We’ve talked about these feelings of mine before, but it doesn’t feel like we ever come up with a solution. I don’t know if I can do this long distance much longer with these constant depressing feelings. Help? Advice? Thanks in advance.
