I am caring too much about what others think of me

I am still fairly new to this app so apologies if I post this in the wrong sub. 
I am just really tired of losing my shit over what other people think of me. It consumes my life and I pretend that it doesn't. I'm exhausted. I sometimes don't even know what the genuine me would do. Does anyone else have similar experiences? I'm trying to get better but it seems impossible at times because I've been living with it for so long; it's not like a switch that I can just turn off in my head. How can I change my outlook? Any words of advice or encouragement are so appreciated. 
Love this community, thanks guys ❤️
