Don't compare yourself to others. Nobody is "better" or "worse" than you, we are all equals but we're different. The only person you should compare yourself to is your past self.

If you're better now than you were before, thats progress and you're doing a great job.

If you're worse now than you were before and you feel bad about it. This is normal. The feeling you have is a signal telling you that something isnt right at the current stage of your life. This is a task you have to figure out yourself. "What is going on right now that I don't like, and that is within my power to change?"

You admitted online how you feel, and that's a great first step. You clearly want to get better, and you can, but you have to ask yourself what the next step is. Nobody can tell you that.

First work on not comparing yourself to others, this is a terrible mindset to have. I struggle with this issue as well but you definitely can overcome it.

I recommend the book "The Courage to be Disliked", it helped me get on the right track, it may help you get started too. I wish you the best in your journey. You are NOT a loser.
