What do I do about my temper?!

What do I do about my temper?

I slam doors, throw things, and scream very often. I have a 10 month old daughter, and I really do not want her to keep seeing me act this way. I don't know whats wrong with me or why I get so angry? What should I do about this problem of mine. I take everything so serious. I feel like a horrible person right now :/

You could have a chemical imbalance...
After my first daughter was born I felt the same way like I wasnt me and sometimes I felt like I was losing control, finally my mother convinced me to talk to my doctor. The Doc gave me some medication to correct the imbalance, which helped alot. (chemical imbalances are common after child birth as your hormones go all off whack) I also had to learn my own little techniques, like when I felt myself losing it I would start counting in my head or sing a certain song in my mind and block out everything else until I felt like I could deal with every thing. I am no longer on the medication and havent been for about 5 years, but I still use my techniques when I feel stressed.
Just think about how much better you will feel, it really does wear on you physically and mentally to be so angry, trust me I know.
Hang in there and keep trying, your daughter needs you and she needs to see you happy and enjoying life with her, she will only be little once....make it count.
I wish you the best of luck!
