I use to be quite sociable and now I'm pretty quiet. I also used to be known for having a great sense of humor and now I feel like I'm really not all that funny anymore. The only times when I am very good socially and funny are when I'm drunk. Which makes me sad because then I meet people when I'm drunk and they find out I'm much more timid and bland when I'm sober. I think part of the problem is me over-thinking what I'm going to say because I worry too much about how other people will react. I had an especially bad day at work today where literally all I said today was "okay", "yeah", and laugh when people talked to me. Then after work a coworker was joking around and asked one of our girl coworkers why she never flirts with me (she jokingly flirts with a lot of us) and she said it's because I'm too quiet and she wouldn't be able to tell if I get offended or not. Anyway, any information I could have to help me with my problem would be much appreciated.

tldr: tired of being quiet and being anxious talking to people because I'm worried how they'll react to what I say
