Letting my brother destroy me mentally and emotionally. He’s younger than me, I’m 17, he ran away from home 18 months ago because of drugs, he didn’t want to give them up. Before he left, I let him use me so much, he stole so much of my money, used to punch me so hard that I started wearing long sleeves to hide the bruises, and I never really made him stop. He got me addicted to cigarettes and vapes, and had destroyed my mental health so much that I had to cease all contact with him, I haven’t talked to him in over 6 months. He spent Christmas Day in the hospital all by himself. It’s his fault, and I know that, but I also feel like the worst sister. I haven’t stopped carrying this guilt since he left. It’s getting too heavy.
