guilt is killing me

1st I smash my daughter's finger yesterday. Then, I did it again today. I got frustrated because I couldn't get her in the high chair and so I let her down put the tray in the floor. I went to the bedroom and my husband took over. This kinda stuff happens all the time. on top of this I was told by a another person that I am more of a friend instead of a mother to her. The said person basically wrapped it up to say I am a bad mother. I just don't know what to do. No matter what I do I am in the wrong in someone eyes. I have no one to talk to and I just want to break down crying and hide in a closet for weeks on in. I don't know if anyone has anything that would help but I needed to rant. If you want to be a rude stob don't bother commenting because we all have problems.
