Is it normal that i'm mean to myself?

To a certain degree its normal. But when you begin self harming, you need to start speaking to a professional about it.

You need to also understand that, you're only human, you're not perfect, and as a human being we're all bound to make mistakes sometimes. It doesn't make you pathetic. Give yourself a break!

It's normal. You are trying to push yourself. If you best yourself up, you will be sure not to do it again and only get better and better.
This does not work however and the logic is flawed.
[i do what you do as well and am trying to stop and forgive myself]
Beating yourself up will only make things worse. Be nice and forgiving to yourself. It will in turn make you a happier and healthier person.

Sadly, I would say so. Only because I do that to myself, and just realized it thanks to your post. Goddammit. No wonder my self-esteem is so fucking low these days. *tear.

Reverend Dimmsdale, have you been whipping yourself?

Its extremely normal in my opinion. It's probably just the frustration r stress. But please don't beat yourself up about things.

I go through the same thing. I have really low self-esteem because I mentally beat myself up over everything. I feel like I make too many mistakes to be considered a "good person".

Just let it go man.

It's pretty normal. Not a good thing to do though. I'm one to talk though, I do this to myself all the time.

I think most people do this at some point of their lives. I do it often. Now, it's obviously not healthy, but I think it's pretty normal.
