I think im a bad mom

I think something is wrong with me. I find myself disassociating from my family all the time. I love them and want to spend time with them then suddenly I want to be alone and have no one talking to me or touching me but I have 2 toddlers and a baby so that's obviously not possible and I go back and forth like this multiple times a day. I like leaving my house but other days I want to sit in my living room doing nothing all day. I will be fine and motivated and then suddenly it feels like to many people are talking and someone is touching me and the TV is loud and I can physically feel myself boiling inside and then I just blow and yell at my kids for just being kids. Idk why I'm like this h
