Cringes around other believers

So I always had bad social anxiety issues growing up. I couldn't be around a crowd of more than 2 people without choking up and crying hysterically. I wasn't raised in a religious household and it wasn't until I met my now husband that I found God! Well fast forward until now, we started going to this amazing church that my husband just so happened grew up with the pastor. The brethren and sisters at this church are so open, warm, and friendly just awesome people. I always feel nervous around them and I rather stay by myself. The pastors and a few close friends are always hosting cookouts and dinners that we are invited to but we end up going and I start feeling awkward or nervous. Especially at the dinner table, talking!! How do I get help with this ongoing issue??
