Awww, Allergies is just (●´⌓`●), I know someone who has allergy, she has skin allergy. And that affect her a lot. Thanks to that she lose weight too because we feel like everything she ate is affecting here. She spent a lot too because of that, had a lot of check up because of that shitty allergies. It sucks when you have that. There's a lot of things that is not allowed.
Anyhow, hope you get better soon, I mean, that allergy to completely disappear is its possible. It'll be better if you get better right this instant.
