summer of lost friendships

so this happens every summer it starts great i'm doing stuff but then all of a sudden i'm out of touch with all of my friends and i get so lonely (and i hate making the first move because i always get turned down to hangout with my friends) and i literally just lose so many friends in a 3 month period and it actually makes me so angry/sad because when i go back to school it's so awkward because i have to start all over again and i'm so terrible at small talk. is this just me?
