My mother called me a trick baby and a ho and expects me to pick up my phone?

Recently my mothers boyfriend ped due to cardiac arrest. He went into a coma for 4 days and during that time either my mother stayed with me or I stayed at her apartment being she was nervous being alone. He ped and we just buried him last weekend, from that time either she stayed with me or friends. My mother has always been a drinker on the verge of alcoholism. Earlier she was cussing one of her friends out accussing them of stealing her keys..she is known to cause drama and yell at people all of the time. I told her how she needs to stop drinking she says "look whatever you call yourself..u trick baby..u ain't nothing but a f(ing) ho" when she kept talking I hung up the phone on her..now she calling and I don't want to pick up..am I wrong?
