I'm Going To Lose My Home.. Please Help Me..

I want to start out by saying I understand this is no one elses problem and if you wish to help me I appreciate you so much! Last summer my mom unfortunately was diagnosed with breast cancer again.. which lead to her having surgeries and time out of work for months.. I helped her with expenses during her time off.. in that time I got very behind in my own bills.. I even spent money on a breast cancer benefit for her to raise money for her medical expenses, and nobody showed up to her benefit besides a couple close friends and family.. we ended up not making a profit at all, and I spent hundreds on the benefit alone.. ever since then I have been extremely behind.. since then I have been completely screwed over financially by friends, I have had to take on responsibility of a home that I cannot afford on my own and $3500 bills a month.. I have been working my butt off and a few months ago I lost my job.. I am in the search for a new one but I will not be able to pay February's rent nor all of my past due bills due now.. I'm at a complete loss.. I am actually more worried about my little brother who lives with me and animals than about me.. I have dogs and cats and I could lose my house...
