stop being so self-critical

I wake up every morning feeling that I living a mistake. I constantly put myself down.. and wallow at any expense when I feel I have failed. It seems no matter how much I try.. nothing I do is enough. I’m a perfectionist and in all the worst ways possible. I have this little tick in my head that constantly tells me that I can’t do anything right. This voice follows me everywhere I go. My confidence is low and I never really fully appreciate myself because I feel that when I do.. I get self indulged in my pride. I end up being arrogant towards other therefore I find it hard to find an equilibrium. I want to remove this voice so that I can live life the way I should. I’m still growing up and I don’t want this habbit take away my adolescent life.. because you’re only a teen for a certain amount of time.. You have only one shot at life.. so I might as well make the best of it rather than staying in a nostalgic state of mind.
