I actually have the opposite problem. I am very firm in who I am (even if I don't share my feelings with people a lot) and I often alienate people because I am unapologetic about who I am. It's caused me problems at jobs before because even if I was good at my job I didn't ever fit in socially with my coworkers and I'm pretty horrible at adjusting who I am and how I present myself to others. I've always been labeled as weird or eccentric.

It's weird though because even thought I won't change my behavior or need reassurance in who I am I still want people to like me and will (for example) worry someone is mad at me if they don't respond to my text.

I hope that made sense.
