Needing to vent.

I'm needing some advice from anyone that can take their time to talk to me. My mother and I just do not get along whatsoever. Last week we were on good terms and now it's beginning to get out of control.
----------------------------
Okay so like I said we were somewhat on good terms last week. I never saw this side from my mom so I thought things were gonna get better. Well I was wrong. Today I woke up early so I can go out for a workout. My mom was on the phone and I heard my name being mentioned so I was like "what the". I go to eavesdrop and my mom and our family friend, Karen, are bad mouthing me saying "I bet she fakes her anxiety" "she doesn't know what anxiety is". Like hold tf up. If I don't have anxiety then why did my doctor diagnose me with it and why am I getting meds for it? They went on about how I get money since I'm unemployed. Karen says "You better watch out she might be stealing money out of your purse!!" Firstly, what the fuck and why would I steal from my own flesh and blood OR FROM ANYONE? My mom kept proceededing how I'm just like my deadbeat dad and that hurt me. Like don't compare me to anyone, especially someone who doesn't give two shits about me. She kept going on about stuff that wasn't backed up by facts. So now I look like some immature 20yr old brat trying to mooch off my family, creating fake problems, and that I have no effort to move out and get a job. I'm just in a tough spot. If no one commicates with me how am I supposed to know what is going on and how others feel? 
----------------------------
Right now I'm trying to act sane. I'm trying to get my life together, be financially stable so I CAN move out. Basically where I'm going on with this is that I just want some advice as to what you would do in this situation. I appreciate those who read and respond.
