Feel like I'm about to have a panic attack

I'm at the point where I'm shaking and about to have a panic attack. I have no idea what to do anymore and I feel like I can't hold in my emotions anymore.

I can't stop thinking about how socially awkward I was this week. I can't stop thinking about how my mans friends (females and males) probably think I'm not worthy of him anymore and I've turned into a freak. I hate thinking about what other people think of me 😕 I try so hard to make these great impressions and if one thing goes wrong I get so anxious and nervous and feel like everything goes wrong afterwards. I think about it for days on end to the point where I drive myself crazy 😨 

Sorry this post probably doesn't make much sense but I'm writing this fast and trying to describe the best way I can on how I'm feeling... but it's so hard to explain 😟😞
