Resetting/relapsing even after eating very less junk food.

This happens with me everytime.
I keep on resetting/relapsing every after 1 or 2 days. I do not eat junk food too much. But when I eat it, even very less amount, I am not able to control my urges and then I reset/relapse.
I do mention that sometimes, for me it is unavoidable to eat junk food, such as in weddings,parties,peer pressure or during special events in my house like festivals.
I do exercise everyday. Please, anyone help me this situation.

 

Thanks for the advice.

 

Actually I usually don't go in events at all until it is very important. I have started nofap around 11 months ago. After around 1 week,my 3rd semester was started. I have ate very less junk food at 3rd semester. All was going fine(I still have resets but never watched porn that time) until my college 4th semester was started.
At that semester, many students are not coming in the college. I felt much loneliness than ever before. So much suicidal thoughts are coming in my mind. Some of my friends are coming, so cope with loneliness, I used to spend time with them. At the time of the lunch, they eat junk food but I don't. When I told them about I am avoiding junk food due to my porn addiction and nofap, they say nofap is bullshit, don't do that. So not to fall in the same loneliness situation, I kept eating junk food with them. Now, 4th semester has ended, I am at home.

Same with my family members too, they also don't understand my problem, my elder brother, especially. He buys so much of junk food. So to avoid throwing of food, I have to eat some of them.
