Weight gain in 2 months due to stress

Past two months have been hell hard for me...from being stressful at work to home..last year i had an amazing weight loss..of 6kgs...now I gained some of them back due to disturbed sleep cycle and lot of stress!! I know with little push i can lose weight..but I am kinda dis appointed at myself..and right now I am spiralling and hating every bit of food I consumed due to stress!!! Please motivate me!! I am feeling absolutely pathetic right now...
