Emotions

The point of these is because I feel out of it my son does things that he's not supposed to do like throws the whole gallon of milk on the floor after I just bough a new one I don't blame him because he's alone I get about 4 hours of sleep & back to work there are days I can't control my anger & I yell at him & there are days I think horrible things but I never have hurt my son I just go in the bath room after I yell & cry with so much emotion I ask my self if I'm a bad mother because of the things I think & there are days I can't manage to control

My anger so leave the apartment and I step out in my balcony to get some air should i seek therapy or am I going crazy? I'm I wrong to think that I need help ? I try to do everything for my son but I can't mange to ever win like I feel so out of this world & I think to my self that sometimes it's not even worth living anymore not that I want to commit suicide because my little needs me & that isn't a way out ! If anyone out these knows what it is to be a single young mother that has dealt with this I would like to know what to do! I want to be a better person a happy person like I used to be I want to be emotionally healthy & be baClean in my feet once more I ask for help !!
