okay i need serious help, i ate so much last night because i was really depressed...help?

i have never eaten so much in my life before.

first i ate chili for supper at like 7:00 pm. then just because i needed something to do made a whole thing of kroger brand chocolate chip cookies. made about 11 cookies from it . my mom ate two....i ate the rest....but i didnt stop there, then i saw these litttle cookies with this lemon filling in them. and i ate five of them. then i ate a rice krispie bar. then got into the leftover chili and ate a couple bites of that.....then i got into the peanut butter and the strawberry jam later that night too....i couldnt stop....

i woke up and i was still full....thats how much i ate. ive been working out all morning, but i feel like im going to be sick because mostly everything i ate was loaded with sugar and fat.

im underweight (age 17, weight 114, height 5'11) and the doctor told me i should be gaining weight but thats def not the way to do it.

im also wondering if that much sugar and fat could cause me to get sick or somthing today.

but what should i do today or for the future to help fix this.

im afraid to eat anything now...and im still full 3 hours after wakeing up today because of how much i ate last night.....i wouldve normally eaten breakfast, but again im scared to do anything at the moment.
