I want help

I have a eating disorder similar to Prader Willi syndrome that makes it so I have to live in a group home that treats this sort of issue. I have been in and out of 2 other group homes beside this one partly due to the food not being locked up and other reasons. Like I said,
my doctor thinks I have an eating disorder similar to Prader Willi except that in the past when I stole food I only would steal one or two things. The real reason I am reaching out is because some of the staff at my group home keep checking the pantry which I know they are supposed to do but they only do it when I'm awake and in my room but when I am in the living room or another part of the house they don't check it. When they walk by my room to check it they always look at me like I stole something even when I didn't. One of the staff has also told the other staff to watch me when I go in the office because there is sometimes food in there also and when I walk by the fridge or freezer they always check it. It just makes me so mad and is the main reason why I used to steal food. I tried talking to people about it but it seems that no one understands or cares. I would appreciate it if someone could respond to this message. Thank you.
