I know it's easier said than done, but try not to think about the stupid things your cousin says. Any nasty shi**y comments your cousin makes about you or to you reflect far more on him they do on you. Doesn't sound to me like he's a very nice human being. Ppl make mistakes. Kind of hypocritical of him to call you out on your addictions or relapse when I'm sure he's totally perfect and had never made a mistake. F**k him. You do what you do and work on being the best you that you can. We believe in you. =)
