I think it's more important that you don't be like you. You sound pretty young, so you have a lot of time and adaptability so you can change if you don't like where you are. Is it easy? No. Can it be done? Yes. Especially if you start young. You need to get into therapy whatever it takes to do that.
I feel you, my friend. I can have a really good time eating cheesecake and watching netflix and then start to curse myself. It's a vicious cycle. I get it. The good news is this, EVERY day is a new day to try. I don't have to worry about doing it just right yesterday but can do my best today. And each day that I make better choices helps. Now, you are writing on the depression forum. I will tell you having watched a loved one become severely depressed as well as always suffering anxiety, that really impacts energy level, motivation, how they've been comforting themselves. Psychotherapy really can make a different. Treating the anxiety/depression as a real thing can give the boost you need to get on track. Do you get enough sleep? Etc.
Hang on there. I am also having depression due to HIVPhobia. But you can make a change! You can have a healthy life by eating healthily, exercising regularly. Don't think yourself as a burden.
