Eating ....

I use to have a eating disorder. Not to the point where I was extremely under weight . But to the point where everyone was noticing . Thankfully i pulled through and started to gain weight . This was about 2 years ago . Now iv noticed I’m having a hard time eating, like I have to force myself to eat . I don’t feel like I’m fat , I don’t feel depressed. I just don’t ever feel hungry. I have been sick lately like with fever and weakness. I thought maybe it was because of that but I can’t seem to get over not wanting to eat . I really don’t want to go though this again . Any advice? I have already been to the doctor. I have a great family that encourages me to eat. But I just feel like I can’t . I’m not at all under weight . I’m 5’3” and weigh 128lbs . I just don’t want to get to the unhealthy point .
