It hard to say goodbye

I need to say goodbye you’ve been holding me back for years. When I use you you take away all my fears. But I’ve been abusing you for far to many years this relationship has to come to and end. I no your not my actual friend. Your my friend when I’m feeling down lonely worthless.But all you do is take and I can’t handle all the heartache. Why me you’ve taken the best parts of me. Soon there won’t be nothing left of me. I’m begging you ,you  have to flee by herion your not killing me.
