Look i dont know you personally- but there is obviously way more to this you arent being honest about (and you shouldnt air it out here)
You said they never did this up until they found out you were using Tren as a 17 year old (not even going to go down why this is retarded)
Are you out of HS? Do they provide food and you just dont like it? Were they aware of the insulin? What type of "food" did you buy?
My little brother said the same shit and it boiled down to him wanting to abuse tren and not liking the food my mom made. If you are out of HS and thats completely normal to be paying rent (hell half the people I knew growing up paid "rent" growing up and it ended up being saved in a fund for them)
How much are they charging you for rent? Like there is so much context - either way hope whatever is happening improves just be real with yourself
