Heartbroken

I recently had some troubles with a friend. Things have been fairly resolved but my heart still aches. I love this friend dearly. More than I should. And he does not want me. I constantly question what is wrong with me and everyone tells me nothing. I cannot trust that. Something must be wrong. My heart is broken and it is hard for me to deal with. It is hard to sleep, I have to wait until I can no longer handle being awake, especially when ever since I met this person I have not dreamed without him being there. Every morning I wake up depressed to the point of sickness. Please be gentle with comments right now. Harshness may break me.
