Anyone on here know about personality disorders?

Last night was bad. We were all smoking and I had too much and my personalities split apart. I was a mess, switching between them and I think it's because I got a panic attack. I don't think it was as bad as I thought it was in the moment but I was trying to leave and people kept talking to me.

I overheard this girl I said bye to telling someone " I think what I just saw were different personalities."

I'm so mad at myself for losing control like that. I put so much effort into trying to assimilate with people and today was a day I feared since I was a kid.

I don't know what do do, how can I function when everyone can clearly see I'm crazy?
