Tired of trying. *rant

Since I was 16 I've helped my sister care for her daughter. At 16 we had a house(a family member owned and let us live there for free), I worked while in school, she stayed home. It was okay for a while, then she had gotten strung out on drugs. I treated my neice as my own and cared for her more than my sister did, to the point she called me mommy even after me correcting her several times(she eventually grew out of it). My sister always had people in and out partying and whatnot. My sister ruined things between me and this guy I dated all throughout highschool (like fr im still so heartbroken over him and i shouldn't be 😭) she stole about $12,000 total from him and bridges just got burnt he couldnt handle my family... theres alot more just ive tried to be there for my neice and put up with my sisters shit for too long. I graduated high school and moved out. Now, Im married and have a 5 month old daughter. Im 20, my sister is 30 years old if that makes a diffrence? I tried patching things up with her because I really wanted to see my niece. Shes already 7 😭😭 I invited her over tonight. she finally shows up and two of my old friends from highschool were in town and stopped by to say hi for a few minutes. when they left she went off about how i dont need to have friends and dont need them coming over to my house around my baby...and i was so dumbfounded all i could think to say was "well... at least there not on drugs" and then shit hit the fan, she jerked my neice up and made her get her stuff and was screaming about how i would never see her agian and that me and my baby could go to hell and said my husband was a horrible father because he wrecked our car a few months ago, which had nothing to do with her so im like ?? okay bye 😂 and then when she does this shit my ENTIRE family disownes me 😒
