An Attack of Insecurities

I have been overthinking lately. Do you know the feeling of wanting to rationalize but the thoughts and feelings are fighting inside. I know I'm worthy of the world but feeling says otherwise, that's I'm not good enough. People around me might contribute to it but I know it is a battle within myself. 

I know I'm beautiful but I don't feel like I am. Even if other people say that I am, there's a part of myself that thinks that they are just saying it to make me feel better. 

A compliment makes me more feel that I am not worthy of those. It makes me crumble like I'm a snail that wanted to go back to my home and doesn't want to meet or talk to other people again. 

But at the same time, I'm trying. Trying so hard to accept it because negativity is just invading my thoughts every time others compliment me or when I compliment myself. Whenever I'm thinking about it, I'm cringing so hard. 

My only question is to have to improve my self-esteem and lessen those insecurities because whenever it attacks me, I always wanted to cry. But when I cry, I feel like I'm crying for nothing. 

Now, I'm in a slump where I don't want to do anything and don't want to think anything. What should I do? 

That is my question but I know I'm the only one who will come up with a solution because it is an internal stripe. Wish me, luck people. 

Me, wanting to be happy and live peacefully is all I can wish for.
