<human>: Give me a shortened version of the text

My boyfriend (21) broke up with me (18) about three weeks ago after dating for about a year and a half because of the long distance. I am having a really hard time getting over this because I'm madly in love with him and he was/is my favorite thing in my life. My heart is completely broken. I've heard all that "other fish in the sea" stuff already. It is not comforting. The only thing keeping me going is the hope that we may one day get back together (although my ex is telling me not to get my hopes up). Does anyone have any advice on what I can do to get over this? I am on winter break for a month and figured I can use my sadness as motivation to improve myself. I'd appreciate any advice/ideas. Thanks.
<bot>: Still completely in love with ex and need advice on how to get over it and how to benefit/improve myself from it.
