Everyday traumatizing thoughts

Every morning I wake up and get dressed for work and put a smile on my face when really, I'm so depressed and upset that I'm mostly home now because of the virus. I hate being home with my parents and family because all I get is disrespect. A couple years ago, it was the middle of the night and I was watching tv and my sister and her best friend and fiancé came home from the club or whatever. They were sleeping over because my parents were in Jamaica at the time. Long story short my sisters fiancé tried to kiss me with her being in the same house, he's half naked, and tried to do it multiple times. I cried all night and didn't sleep even called out of work. I told my parents and my brother but at that moment nothing could be done. My sister then found out and then Yelled at ME because I told my brother. I was scared. I was so in shock. I was a minor also at the time. Anywho, my pre at or family didn't so shit! They didn't care about my feeling and not even till this day ask me if I was ok or how I felt. And they still got married. Everyday I see him I feel so uncomfortable in my own home. They sacrificed their daughters happiness and comfort for their other daughters pedophile husband. My whole family loves him and I have no idea why. Maybe cuz he's rich. But my feelings were even considered. Every day I cry and I'm traumatized by this and no one cares. Life isn't for me. I shouldn't be here on this earth. But the day I die is when everyone will love me how I loved them.
