Hello agra! Welcome, im new here too.
I think what you are feeling is normal. It is difficult for anyone to change their way of eating and stick to it. What always helps me stay on track is going to the gym, even if its just to walk on the treadmill or lift some weights. It motivates me to stay on track for the rest of the day. Oce you get into a routine, each day it will get a bit easier to get yourself moving. Also, if you find that you keep messing up with your food intake, try to figure out what triggers you to go for these foods and see if you can't find ways to counteract a binge (i.e. not depriving yuorself so much that you break or finding lots of healthy snacks that you actually really like)
Best of luck and I will see you around!
