[ Other - Health ] Open Question : how to get rid of this feeling..?

okay so in june RIGHT after school was let out i went on a carnival cruise :D there was nothing better than being in the Caribbean with gorgeous women etc. but while i was on the cruise i met ALOT of amazing women they were all really nice/hot and NOTHING like the woman that i do to school with it makes me really depressed to get off a cruise after meeting nice people and then looking at the people from my school and just seeing how the women/guy are, there slutty or assholes to others or scummy and the women just play all those unfun head games how should i get over this since im like depressed that i go from amazing to like trash? :/
