Bridesmaids Help? Feeling Really Sad I Don't Have Any Friends Or Cousins

We only have three bridesmaid & three grooms men. My fiancé has his cousin and his wife and his best friend and his wife in the wedding party i only have my guy cousin & his girl friend which i'm really close to. My fiancé wants to include another friend and his wife so it can be 4 all total and i'm feeling really sad because i only have my cousin from my side and all his friends and cousin on his side. Originally my brother and sis n law were going to be part of it but then she had jealousy issues i was getting married since she didn't get married so my brother decided not to be part of it since she was being negative about everything. I'm not close to my other cousins i stopped talking to my friends i had in college when i started dating my fiancé and i just started talking to one of friends from college this week but i will feel really awakred to ask her to be a bridesmaid since we just started talking again after 3 years. Whats your advice?
