My weight

I have been gaining weight and my family is skinny and I'm the odd one out. My mum is a health nut and my sis has always been skinny . I hate it they put me down about my weight. I work nights and it's hard to find time to go to the gym , my boyfriend is supportive towards me I'm trying to eat healthier but its hard. I've been stressed about my x husband what he did to me causing me to worry about this new relationship. It's me , I just feel like my weight is getting to me or how I look now. People are noticing I've gained some weight now I feel depressed on how I'd did this to my self. Plus my boyfriend now me and him are and have been trying for a baby it's not happening because of our work schedule and hea been stressing over trying to have a baby
