I want to slap this ***** so badly! Help?

so my friend got almost evicted. She has until the 14th of this month to find 7000 to pay her rent. (yes shes that irresponsible). Trying to be a friend, I offered for her & her daughter to stay with me & my daughter. Since shes been here she never once bought food for her daughter & had the audacity 2 ask me 2 wash her clothes. I didn't mind doing those things 4 her daughter but she didn't even say I'll buy some detergent & fabric softener 2 wash my clothes. My things is u could wash ur clothes 4 free but buy ur own soap. She's trying to take advantage. Mind u this ***** has a job & I am in between jobs right now. Last night I told her 2 let the kids sleep on my bed cause i washed the sheets for my daughter's bed & she had the nerve 2 stay in the bed w/the tv & the lights on while talking on the phone knowing the kids had 2 get up for school this morning.My child was practically at the edge of the bed. What would u do? I'm 26 shes 24
