Bad home life !!

I'm a 17 year old Junior. My grandpa died in December of 2019 and my grandma died in January 2020. I miss them both so much and I have develped bad coping skills. I use to spend the Weekend there and when it was unsafe at my house. My dad is an alkoholic. I have really bad social anxiety, depression, and ptsd. My bad coping skills include not eating or eating to much, self harm, exessive sleeping, and drinking.
