Can someone please help me?

Hi.
At this moment I'm very upset at my self. I had not weighted my self in months. . Just been running around and all.
I finally did and I was surprised to find out I am at 253lb this is the biggest I have ever been. I notice that I can't tie my shoes or pick up something from the floor with it almost passing out.
I don't have time to go work out. I am tired of my parents calling me "cow or piggy"
It makes me very upset enough that I avoid taking to them.
So far I took all soda of my diet and I cook my own meals (No more fast food).
Any advised on losing weight is very much appreciated.
