I'm 14 and I've done some bad things and now my mom is very very very angry with me what can I do to make her forgive me I've written letters and done all the things she has asked but not even a little forgiveness the bad things I've done are having a bad attitude being rude to her and my teachers and my sister I want her love again she has also taken the punishments to the extreme I just want her to talk to me again..

I doubt she hates you. If she hated you, she would not care enough to punish you or be angry/disappointed in you. Parents who hate their children rarely care enough to be angry or punish. It sounds like you have upset her, and disappointed her. That makes a parent angry, it makes us feel like WE as parents have done something wrong to MAKE you rude and disrespectful.

That is not the case, YOU made your choices, and now you are dealing with the consequences of it.

May I ask what punishments you find extreme? And what has been done about your behavior?

It sounds like you know you were in the wrong, and that's very good, that's a huge step to being a mature responsible person. It may take your mother some time to move past this.
