how do you handle insecurities?

After I moved out from my mom's house insecurities are a piece of cake. My confidencev just sky rocketed.

Before, I didn't realise I was insecure, I though I was normal. I just thought that it was common place to be put down and have everything I do contested because it wasn't done the right way. Now I'm married and I won't fall for these shenanigans.
