Bothered af. I need to vent , calm down, and go to slp. I dnt knw if its just me or if it is what it is...
I have a toddler(2myself for now...), a 5day full time job, a mother in law, a blow up mattress, and family states away.
My mother in law & i clash alot. I knw why , when , where and how. I dnt knw where to begin its alot.
Its sooo freaking petty iM over it.
My room is a small to bedroom apt is the living room. My back hurts a lot. I stand up alot at wrk and my daughtr does not have a crib. We share a air mattress that takes up the living room with said living room furniture. Mothr in law comes bck from "vacay" and got mad cus iWas redy to blow my mattress up. She asks y i do that. I say cus i really don't want to. She says well yu gta do it every night. I say well ima do it when im ready. She says its not fair. I say thats not my fault(for a reason) and she tells her son(myboyfriend) w.e she tells him and he calls me sayin iMake his butt hurt(lmao). &hangs up on me. And its irritanting bcus iAm just not comfortable. I never shuld have come here. IFeel lik iCuld b doing btr whr iM from and iDnt wanna keep jumping in and out of stuff. Strting ovr here and there. Then bck ovr here. I have to have a stable lifestyle for my daughter. How can iDo that when iHave no choice to depend on strangers.? And iM mad at myself for going thru with this. Trying to make someone else happy and separating myself for no reason. Its my fault. I feel stuck and iKnda am.

So what can you logistically change here?
