Something snapped inside of me, i didn't care anymore

So I went to the casino today, I didn't gamble because I can only gamble next year but it's also part Arcade and food court. This is beside the point but I love casinos, the flashing lights, the grandiose nature of it all, I even like the security check in. I feel so important and I love it. I don't care that they only make you feel important to take your money, I love it.

Anyway my actual point is that it got to the point where we were heading home and we couldn't walk across the gambling area so we had to go the long way around. So me and my friend were talking and he said that I should walk to someone and say that they look like someone I know just to mess with them a bit. I wanted to make it interesting and he said that if I did that he would pay me. So I saw the perfect victim and I should've been nervous but I just kinda went with it. I told him "hey do I know you", " are you my cousin " he actually believed me and went to ask his dad so I ran. 

The point of all this? I want to rid myself of any anxiety when talking to people so I'm gonna try rejection therapy, which is where you ask Strangers things with the hope of getting rejected to desensitize yourself. For instance you would ask a stranger to buy you a burger because most probably they'll say no. I'm gonna do that, I used to do shit like this all time but I started getting really anxious to the point where I couldn't even say yes or no without stuttering or freezing. So maybe this will help me out
