You sound like me. 25 housebound for five years. Eating disorder, avoidant personality disorder (a greater form of social anxiety disorder basically) and agoraphobic. I can tell you I’ve lost weight and gained weight now I’m 330 pounds food is how I cope. I lost 100 pounds a couple years ago but because I hadn’t cured my mental health and food is my coping mechanism even though I felt better at 100 pounds lost but my issues where still there. I honestly don’t believe losing weight is what’s going to magically solve our issues. It can help gain self esteem, but unless the mental works done that’s where progress needs to be...I recommend therapy, I wish I could go but I can’t afford it.
