What You Eat in Private, You Wear in Public

Hello, I have an obscure disease that has resulted in having zero appetite, which has resulted in a 40 percent loss of my body weight, which has obviously been very revealing to my community. I may have mentioned that many in my community began shunning and shaming me once I began losing weight, actually being told that I look like a Holocaust victim and should wear make up so I look less gaunt. For what it is worth, the person who said that was once someone I thought was a friend, but is no longer. I have finally been able to deflect this behavior, because I have gotten used to being "thin." I never struggled with a weight problem, my usual weight being around 125 lbs, and now it is hovering around 95 lbs at best.
I literally have to remind myself to eat, and then when I do eat, I have to be careful because I have ulcerative colitis. I am now making a list of those foods which create problems in this regard. I have seen a nutritionist who has given me some very good ideas, but I did have to admit to her that I did not see myself eating the requisite 2000 calories per day. I have tried eating small meals throughout the day, but often "forget" to eat, and then when I do remember it is difficult to do so. I do not have celiac disease. While I have gotten used to this androgynous body, I am still uncomfortable about my appearance, just as I always have been. I have overcome the insensitivity of those I run into during my walks, but there have been times when a person comments, "Why are you so thin," or "You look better wearing make up, keep it up." I hold my tongue when I want to fire back and say, "Why are you obese?"
Does anyone have any ideas about how I can increase my calorie intake without trying to eat a lot at once. I eat a lot of those Perfect Bar protein bars, thinking that the 20 calories they provide are at least enough for one day, but I am getting worried about further weight loss, just as one might get concerned about weight gain. My brain does not tell me to eat unless I force it to. Does anyone have any suggestions in terms of protein bars and things of that nature that I can make myself, as the Perfect Bars are quite expensive. I am getting to the point where I feel, "well, maybe I should just give up eating all together," and this is a scary thought. I am starting to tell myself that no one will ever want me for the sake of my weight. Not that I am looking for a "mate" but it would be nice to hear a compliment once in a while. I wear nice clothes, always look "put together" and things of that nature, but now that I am beginning to lose more weight, I am getting a bit concerned.
Thank you.
