Why do I always think everything I do is wrong?

It might be because how your parents raised you, try to force yourself into thinking that there are things that you do well and things you dont do well.

I can definitely relate to how you are feeling. I can say that, for me, it may be my lack of self-esteem. I will admit that I need validation from other people first before I engage in an activity. This can be fixed, I feel, by placing more confidence in ourselves. Perhaps, our fear of doing the wrong thing oftentimes causes us to do the wrong thing. But when we have confidence in our own abilities, we act more competently.

It can be beacuse of depression or etc. mental disease. im sure about that it is not about you at all.

Maybe because you have low self esteem or maybe because someone created that idea on you, telling you that many times that you started to believe in it

Having low self esteem and how you feel about yourself and feeling helpless in yourself could be a factor, you need to find out why you feel this way. Talk to your doctor you may be surprised your not alone.

It sounds like you may suffer with low self-esteem. I'm sure that you are doing fine and believing in yourself will help you to know if you are right or wrong.

Because you may have been conditioned to think that way and just are not conscious of it. Think who in your life might have been critical of you.

Insecurities are the strongest when you're completely focused on yourself and what you do or how you do it. Looking at other people, not judging them but just observing them and talking to them and sharing with them always lets me know that I'm not the only one who doubts themselves. I'm an introvert but I try my best to come out of my comfort zone and force myself to see that even my worst mistakes are easily replicated and dealt with by millions of other people. That makes me stop being so hard on myself and being so pessimistic. It makes me more confident even, sometimes.

It can really depend because there can be so many factors that could be contributing to these thoughts. These aren't questions that need to be answered out loud, but maybe to think to yourself, is there a history of bullying and abuse? When did these thoughts start? Is there a trigger for these thoughts? A lot of the time with bullying and abuse for example, when we hear things we eventually begin to believe it. Some negative things only need to be said once for a person to believe it, unfortunately. But at the end of the day, you aren't doing everything wrong; and even if you were doing things wrong, it's okay to make mistakes. It's a part of being human.

I've gotten negative feedback from others consistently from childhood on. I realize now I wasn't doing what they wanted, but that didn't make me wrong.
