Why do I always think everything I do is wrong?

Your mind can twist what you think into something negative because you constantly tell yourself you are wrong. You continuously tell yourself this and it becomes set in your mind that what you're doing is wrong.

Ask yourself this. Am I the one who is wrong, or is someone telling me that I am. Am I causing myself to make these decisions or is someone/thing making me?

Maybe that goes back to a bad childhood memory or emotional abuse done to you by someone (usually one of the parents who wanted you to be perfect or a school bully). We all have those times when we think everything we do is wrong, but sometimes it becomes a part of our identity (a destructive part) and we need to sit down and figure out the factors (people or events) that destroyed our confidence this way. If you're unable to figure it our on your own, you can always sit down with a therapist and let them figure it our for you :)

This is easy to answer and it by the response I normally get. Then the vicious circle starts. The question is where the truth starts or finishes. Is it better to ignore the fact people don't gravitate towards me and get on with the lonely existence. Or stay in bed........

Lack of confidence and self esteem, bothering what others think, fear of embarrassment and Bothering about Physique. All these combine and feel you are wrong and not worth of

Because we are our biggest critics. I have had to learn that it is ok to set goals and to push but I also have to speak life and encouragement.

Because you are not trust and believe yourself you are think that if you do it that become wrong for yourself

Maybe because you fear that you're doing the wrong thing, you have to believe in yourself and be confident!

You are your own worst critic! Stop being so hard on yourself. Do or write down the things you are good at. Focus on your strengths and not your weakness of what you can't do... just yet anyway. Because you can do anything!

It sounds like you have some anxiety. I can't tell you why you do the things you do, but maybe you can try to write things down when you think you are being "wrong" and then write a list justifying the things you do vs explaining why they are wrong. It may help you get some perspective.
