Motivation

I NEED to loose weight like I don't hate my body I have my good days and my bad days with it. My belly is big and saggy due to having 2 children in the space of 2 years so didn't loose the first baby weight before I got pregnant the second time, I'm around 200lbs now and then I haven't worked on myself due to being a SAHM to a 18 month old and and newborn who are now 3 and 19 months old. Then we went into lockdown last year when my baby was 9 months old and yeah I've put on so much more weight, my jeans are tighter I can see it in my face etc so I need to do something about it. I know exactly what I have to do. I need to stop eating crap food, snacking on rubbish, reducing my portions and stop eating take aways. That is my issue. I'm in the house all day everyday apart from a quick walk to the shops if we need something or a trip to a field for the kids to run around for half hour. But apart from that I'm at home. I eat crap all day, don't drink enough water and I tell my self I shouldn't eat that, I don't need to, I'm not even hungry but I do it anyway. And if I try to convince myself not to eat it I am constantly thinking about it until I eat it. I'm thinking of the summer and this year my children will be 3.5 and 2, which are good ages for days out etc and we will be able to have beach trips and everything and I want to be able to fit in comfortable clothes and feel okay with my body instead of staying in jeans and a hoodie all summer because I can't wear typical summer clothes because I hate the way my body looks and feels in them. I just can't shake eating all the wrong things. How do I do it. I do it for like 1 or 2 days then I give up because the chocolate in the fridge seems more appealing. What is your advice please?
