Regret being a mom?

Am I a bad mom if I feel I regret having kids sometimes? I just feel so overwhelmed. I have no time to myself. They're always making noise. They're always messing around. Even when I repeatedly ask them to stop. They won't. It gets to the point where I'm screaming because they won't listen. I give them time out. I threaten to take things away. I try everything and nothing works. My husband and I are always irritated. They just don't behave. I'm at my wits end. I often think if I didn't have kids I wouldn't be so angry all the time. I think of all the free time I would have and what I'd be able to do if I had no kids. I'm envious of my friends who get to go out whenever they want and I can't do that. I didn't want kids but life happens and I became a mom. I don't know if I was meant for this. I don't have the patience. I'm always over stimulated. I think a lot of how I feel has to do with the fact I don't get out by myself or my husband at all. We have no village. No one to take them when we're overwhelmed. We haven't had a night out together in nearly a year. I love my kids so very much but some days I just could run away.
