My Crush

So lately, my crush and I have been hanging out a lot more lately. We both know how we feel about each other, and we've gone on one "official" date. We hold hands and cuddle a lot, and we've known each other for maybe 3 or 4 months??
Anyway, for the amount of time we've been spending together, I find myself being nervous and restless whenever I think about him and a little more relaxed around him, but still really nervous. Well last night we were hanging out, and I went outside to talk with him about something and there were multiple times he seemed about to kiss me but I was too nervous and scared. We didn't kiss, and last night after he went home, I was having a minor anxiety attack from my confusion for my feelings for him. And even today I'm still nervous and shaky and scared, and i dont know if I fully hate these feelings I'm having. I'm scared but I don't know why I feel scared or nervous. I'm just looking for advice at this point; is dating supposed to be this nerve-wracking while also exciting at the same time??
