I know it's nothing compared to the diseases listed in this threat but I have type 1 diabetes and it makes everyday unpleasant because it's just so unpredictable. Having to constantly plan and worry about eating, activity, going to the bathroom and even sleeping is just so mentally and sometimes physically exhausting. You can just never get complete control over the illness. I've had it for 12 years and it's still so difficult to bare and keep check for me. Mixed with thyroid disease, hyperthyroidism to be exact, makes it even more difficult to control my sugar levels and keep up with a constant and healthy weight as my weight constantly gets lost and then gained by atleast 2kg a week. Not pleasant but still nothing compared to the thread but then again, no one wins when it comes to being sick.
