Single mom at wit's end and bottomless pit?

I'm 25 a single mom and a year and a half after a divorce due to ex husband cheating numerous times, I am left with sole custody of our daughter who is now 3. With no where to go and options VERY limited I am stuck with my parents. Yes, I am thankful that I can live with them BUT there are so many issues living with them that I almost think my daughter and I would be better at a homeless shelter (being my only other option at this point). This past year I've been in school trying to finish up towards my degree and had money from a student loan that helped with costs of living, so I was able to get my own small apt. for daughter and I. That fell through, and after moving over 3 times this year I am right back at square one at my parents. My mom has rx drug dependency and is groggy and sluggish most of the day and my dad tries to avoid being home by working or being gone. Both parents are emotionally unavailable and I have no one to turn to for advice, support, etc. My 3 year old does not listen to me whatsoever and I find myself so stressed out being around my parents that I am not able to raise her or give her what she needs right now. My mom undermines my disciple towards her and whenever I try to discipline her my mom automatically tells my daughter 'it's okay poor baby'. Like I'm the bad guy for teaching right from wrong. I lose my temper and just can't handle it. I dont know what to do anymore... I feel like a failure as a mother, a provider and as a person in general. I havent been able to find employment and with limited resources and a whole year of seeking istance and no luck my daughter and I are at the bottom of a pit right now. Everything seems hopeless and if i could just find a place for my daughter and I to live peacefully and without constant stress and me recieving verbal abuse from my mother I believe our lives could be somewhat normal or at least stable. How do i handle raising a 3 year old in this environment, when my mom pushes me to my wits end and no matter how hard to try to block it out it still gets to me. i just dont know where to turn to anymore, who to ask for advice or how to even keep going anymore!
