What’s wrong with me :(

Ok so i’ve noticed that I can’t really laugh around my bf. and ik he tries really hard to make me laugh but I can’t. like we’ve been dating for almost two years. I laugh when we r together in person but over the phone I have such bad phone anxiety I like cannot laugh. it makes me think that I might be slightly on the spectrum? i’m a little late to understanding jokes too. I also have some other symptoms such as sensitivity to certain sounds and social awkwardness and eye contact. in person the laughing thing isn’t an issue but when he isn’t right in front of me it is. idk this is kinda embarrassing and stupid to even be posting this for. just something that bothers me. :/ i’ve always known I was a bit different and I know that when people meet me they can sense something is slightly off. when my bf and I have difficult convos, I clam ip and barely say anything. it’s bad and idk if there’s anything I can do?? maybe it’s just low self esteem?
