i don't feel safe

i don't feel safe people around me, they are so toxic:< my friends also , not like before. they don't know what privacy is :(( my one friend send my drunk live to my ex and didn't even apologize about it, i feel so a shame after because i drink an alcohol also my ex feel pity to me. I dont feel safe cuz that one friend giving me a not good attitude, i know she have a personal problem but please she should mind her attitude towards to people she meet, i understand her why is she like that but ofc she should understand why my attitude sometimes is not approachable. It feels like i exist to understand people but it's not fair not to understand me like I DERVE TO UNDERSTAND TO, they are so unfair;// she's one of my closest friend and it's sad that i don't safe around anymore://
