<human>: My boyfriend and I have been dating two weeks shy of 6 months. I'm 17 and a junior at boarding school whereas he is about to turn 19 in a month and is in his freshman year at college. When we're both home, we live 1 1/2 hours apart, when we're both at school we live 2 hours apart and when I'm home and he's at school, we live 3 hours apart. We started dating in August before he left for school and we were so, so strong and I care about him so much. For my Winter Break, I went home and at home I got very depressed and this had a negative effect on our relationships. The way he puts it, now he feels we're just "going through the motions" and we really are. I've been back at school for about a month now and we saw each other a lot over break, but it's also different when he's at school. He even says that when he's at school he is more "hesitant" with me and our relationship. Today was the first day that we talked about it and confronted our initial denial, because it really has been going on too long that things have changed. I really believe it's because I'm depressed, but I don't think that's all he thinks it is. 
Extra Background: I met him while I was still dating my ex, and in the process of falling in love with this boyfriend, I eventually got over my ex, but didn't give myself adequate time in between to reset myself. Over the course of our relationship now, I feel that I've adapted his personality into my own and lost sense of myself. I am so confused about who I am right now and stressed between school, home-life, and now our relationship... I don't even know what kind of music I like to listen to anymore. 

Where do I begin? What can we try to do differently in this semi-long distance relationship? Help? :( I don't want to lose him, but I just need him to be as happy as he's made me. I need him to know how much I love him.

Give me a shortened version of the text
