I sent an “intervention” letter to a drug and alcohol-addicted family member and not I want to take it back!?

In a fit of passion and anger, I wrote an “intervention” letter to a close family member telling them I am sick of their alcohol and drug use, and that it is the cause of all their problems. I also insinuated that they might be mentally ill, not in a mean way, in a serious way (I truly believe this). This family member has been in and out of prison and had problems all his life. The issue: the night after I mailed the letter, I talked to the family member, and we cleared the air and everything, and he is going to seek treatment, attend church etc. Now I am dreading the moment he gets the letter, because some of it comes off as mean. I have been dealing with his addiction for a long time, and I finally just had to open the floodgates, but now i’m concerned he will feel isolated, guilt-ridden, or depressed due to the letter. What can I do? Should I ask him not to open it? Or is it good for him to have in writing my condition for our relationship (I told him I would no longer accept him drinking around me, etc). I just don’t want to kick him when he’s down! He’s been suicidal in the recent past! Help!!!!
