Am i fat?.............?............…?

Im 18.Last june i was 134lbs,30in pants.i dont work out or anythin.Was 5'6 and still am. Now i started college in the fall and was shocked because my friend was cracking up and told me to go wayed myself,thought nothin of it. Im now 158lbs,i couldnt believe it,i thought i just put a bit of weight on,i now barely fit in 32in pants. I should have realised when my size M shirts became tight. Would i be considered fat,or kinda thin still.
Ive never been fat my whole life but just looked in the mirror and i kinda got a whole double chin thing goin on,is this overweight or fine?
thanks
