<human>: I am an 18yo male, and he's a 19yo male. We had been friends for a few years but we really got close about a year and a half ago. He came out to me in August of last year and since then we've grown closer than I ever have with anyone. I know we're both young and I know some people cringe at the use of the word "love" in such a seemingly insignificant context, but I really do love him. We never really developed a full relationship, and I think it's mostly because he's too afraid. I know that he has not fully accepted that he's gay yet, even though with me he has no reservations when it comes to talking about it. 

One thing I should mention is that I have had crippling, life-interfering anxiety because of him for the past few months, and in an attempt to make him happy I switched to an extremely restrictive vegan diet and have lost 30lbs so far. For context on that, I am 5' 11'' and went from being 180 to 150 over the course of about three months. Whenever I think about him moving away and going off to college I am paralyzed with the fear that we won't ever talk again. We always tell each other that we're going to spend our lives together regardless of whether it means something as serious as marriage or just a close friendship.

He's moving away in three days, and although it may sound like our relationship is very unhealthy for me, I am completely devastated. I don't know what to do with myself. Last night I had my final time alone with him before he leaves and it was amazing. We played video games and talked and just had an amazing time together. Then I told him I loved him, and he said he loved me back. I don't think he meant it like I meant it, but that was the first time he's ever said that to me.

If you have any advice or questions please send me what you can.
