I don't know what to do

i am 16 yr old boy. i dont know what to do and have nothing to look forward to. exactly on our 6 month mark, my gf have broke up with me a month ago, the breakup was really out of nowhere and i loved her so much. now that a month has passed i feel like i will never forget her and by the looks of it she has already gotten over me. i have like a one good friend and couple others. i live in a small town with nothing to do. i have work that is related to my studies and its really rough. my daily routine is work and sleep mostly. the worst of these is probably the breakup, as we broke she said she still loves me and now it really doesnt seem like. she doesnt even answer to my messages anymore. i dont know what to do, i feel really hopeless. upcoming summer is not good either. i have never really thought about it before but it has came to my mind that idk if i really lots to live for rn. this maybe just kind of a moments shock post, but rn i feel this way. i might already regret tomorrow morning. hopefully this is the right place to post this
