Cant stop smoking,cant lose weight🙈

Anyone whos been here before? how did you just one day quit and decided to live a healthier lifestyle,Iv been trying to work out and immediately after I'd light a cigarette🙁 and after the cigarette I think fuck it let me get myself a cheese burger😳so embarrassed! Iv been trying to get healthy for 2 years and unsuccessful,I don't like these work out apps tho and don't like counting calories so I were to be on a diet Id basically just eat whatever is in my fridge just a much smaller portion😬diets are expensive ladies and I'm on a super duper strict budget,just a stay at home mom who's unemployed(don't judge)😖 Just trying to be a more confident woman and love myself instead of feeling like this fat Blob!

Any tips at all!?
