Will the summer heal this year's drama in highschool?

im a sophmore i highschool... next year junior. ive been through soo much drama and so much backstabbing and fights with girls and boy... and ive been through such a mess this year... and ive never been this way.. always the quite normal chill girl who did their own thing but i guess i craved attention this year and reacted to stupid stuff and created nonsense.... summer just started and we have 2 and a half months of summer break.. when i come back for junior year will ppl forget it and if i start acting chill and normal and forgive the backstabbers... will everything be cool? will summer cure the crap?
