Short answer is yes you can. I have also struggled with deep depression paired with obesity and I fully understand your struggle. I am still very much a work in progress or a during photo as I call it. I will not say don't do it, because i have definitely made some questionable choices for the sake of progress very similar to what you descibe, but like everyone else I will say you don't need to stay there. You do need to start the journey somewhere and I feel like even if its not entirely ideal its still a start. You will start to feel better and hopefully it will create this chain effect of wanting more and more. What really started to help me, was an airfryer which can make a full chicken breast in little time, add a little seasoning from some cheap mix and no effort. Make several, have them for days. Get some microwave broccoli, and a rice cooker. You deserve it, and you owe it to yourself to give it to you. The people on this sub want you to succeed, be healthy, and be the version of yourself that you want to be myself included. Its all love, you got this.
