I am 18, 5'5, 32in waist.

june i was 134lbs but my friend said i was too light so i put weight by eating junk food and fast food since then and now im 156lbs. Is that overweight,i just got carried away with eating. Now i am up 2 pants sizes and all my clothes are tight and i dont wanna buy new ones but now i have this gut that is soo annoying,i have never been fat in my life,my stomach is all jiggly and big. what do i do,buy new clothes?or just keep putting on the weight?
