How do I have fun when all my friends are drinking/drunk and I can't join them?

I'm a 23 year old female. I have always casually and clily drank with my friends, boyfriend, girlfriends and family. Since I turned 21 I stopped drinking out of control and rarely drink so much I puke. 3 months ago though I had a panic attack that has affected me so much I cant drink. A week after the attack I had a beer and a gl of wine over several hours and that night my mind took me on a ride. I was so low, so depressed, so insane feeling. It took me over the edge and I could understand, for the first time, why someone would want to take their own life, that is to say if the feeling I had continued. Since then I've been feeling better but the trauma ( i guess you could call it) of that night and the knowledge that alcohols a depressant and a trigger makes me very weary to try to drink again. I want so much to join in social drinking and enjoy a nice cold one here and there but I'm so worried it will take me right back to that spot 3 months ago. Ive made a lot of progress and dont want to ruin it! In time I think I will be able to drink again but Im so nervous to have a drink all the same. It blows going out and being the sober one. Its fun at first hanging out and laughing but by the end of the night im still stone sober and everyone else is sloshed. I have become resentful that my friends and boyfriend can drink and I cant. It turns me sour sometimes but I dont want to not hang out and get rid of my social life. I want my social life ive had with peers and the social life I feel i should be having back. In the meantime though, how do I have fun and not resent them? Has anyone else been in my shoes? Had panic attacks and alcohol intolerances because of them? Id love to hear your advice
