Had kids young and now I'm over it

Just as the title says I had children when I was young and I'm just over it now I'm over being in a relationship I'm over being a mother like I just don't want to do any of it like I had a complete melt down the other day and told my partner that they needed to just watch the kids and I basically just packed the little bag and went to a nice hotel for 2 days then went to my mother's house on the 3rd day and then I came back home and even when I came back home I just felt so sad and depressed at the thought of even going back home I don't know what to do but at this point I am just over it I just don't want to do any of this anymore I kind of just wish that my partner would just want the kids all for himself so I can just go about my own life and I guess it's cause I didn't have a real youth or young adult years to enjoy so I don't know I just woke up recently and ever since then all I've been craving and desiring is freedom to travel, fuck the world and not have anyone to care for anymore...everything else beyond that just depresses the absolute fuck out of me...I am happiest when not around my partner or children but when around them, I just want to get away from them all
