I have an anger problem directed twards my husband and one year old son. how can i fix it ?

I am 20 yrs old i got pregante a few weeks after i turned 18 and marrired months later to a guy that i had been with for four years, i have already been diagnosed with bi polar and add but since i had my baby i have developed post i think because of my mental history, the fact that i had a c section after 28 hours of labor and my son hated to brestfeed so it only lasted 1 mth and 1/2, so now my son is 1 yr old and i still havent shaken this the depression is'nt so bad anymore but know im am left with a lot of anger and i take it out my husband and son. my life right consists of a 1 bd apt and being alone all day with a very hyper and defiant baby, so sometime when he's just into everything and destroying my house and crying i yell and scream because i am just on a constant boil this only happens maybe 3 times a week but i am scared that my baby is going to start to fear me and hate me. i need tips on controling this horrible anger it's destroying my life...i used to be so much happier
