Hello AureliaUni: Thank you for bringing your concern here to PC. I see this is your first post. Welcome to Psych Central.

You asked why you feel everyone hates you when you mess up. I'm not a mental health professional. So I can't offer you anything in the way of an authoritative response. However my personal non-professional thought on the subject would be that there may be 3 or 4 different possibilities here. Two possibilities, just "off-the-cuff" so to speak, would be that what you are experiencing might be symptoms of depression & / or anxiety. However two additional possibilities might include: low self-esteem & what is referred to as childhood emotional neglect (CEN). At least these are all subject areas you might consider looking into further. Of course to get a professional opinion you would need to see a mental health professional, perhaps a mental health therapist or a psychologist.

Here are links to the self-esteem & the Childhood Emotional Neglect forums here on PC in case you'd like to take a look at them:

One thing you might do, here on PC, is to take some of the quizzes & tests that are on offer. There's a link to them in the banner at the top of the page. However here's an additional link as well:

And then here are links to 6 articles, from Psych Central's archives, on the topics I've mentioned plus links to 2 articles that offer tips for how to stop beating yourself up:
