I can relate. I am not as lonely these days as I used to, but I have been.
I have really bad lungs. I have chronic asthma and a plethora of respiratory ailments and allergies including oak pollen and heavy smoke, dust and animal dander.
My lungs have collapsed before, which is no fun. I had my bronchial vessels burst one, which filled my epidermis with air bubbles. I could rub my face and it sounded like bubble wrap popping. >,<
I am so used to being sick, but its no fun. And thanfully I feel a little better today and I have certainly been sicker before. But it still sucks >,<
