Winter Weight and Break ups

So, i am probably living in one of the coldest capitals right now ... -30 being normal on a daily basis here during winter. And not being able to run outside, plus a horrible break up led to a few weeks of munchin'... And so yeah, at a nice size 6 i am feeling bloated AF. I am not the tallest of people and in an Asian country, where everybody is a 00 or a negative 1 .. I feel fat AF.. Some of ladies in the stores don't let me try on their clothes coz they are afraid i might rip it. Any ideas on what i can do?
