Please help

So I’m 14 currently being forced to recover from anorexcia and I had my appointment and the doctors were deciding whether or not to take me to hospital because I’m still losing weight and my heart is bad but I miss not being able to eat I loved it I might sound crazy but I do and one day I ate a MacDonalds wrap so it was a healthyish small meal and ever since I feel like I’ve gained all my weight bad and I cry every night. Anyone got any ideas on how to get better or stop feeling this way? Please help
