What is the worst illness or disorder that you have ever suffered from?

diabetes

I've been very lucky and haven't really ever gotten sick with the exception of the common cold or the stomach flu, but I do have tendonitis in my left wrist and it has recently started forming in my right wrist.

An endocrinological disorder. Not fatal, but very inconvenient and uncomfortable, and has sucked up thousands of dollars of my money (before I had health insurance) and many hours of my time.

Autism.

Clinical depression, without a doubt.

It depends what you mean by "worst". The worst as far as seriousness was probably the Rubella I had when I was two, but I don't remember it. I had appendicitis a few years back which is relatively serious but it wasn't terribly painful. If you mean worst as far as what I had to go through then it was probably this horrible strain of the flu I had about two years ago that killed off half of the local nursing home. I have Intermittent Prophyria which isn't dreadful because I've learned to live with it but its worst in that its an inconvenience I'll always have.

Sinusitis just 4 weeks ago... very painful.

asthma that needed hospital treatment. I had to suffer for 3 days before I realised I had it. Terrible experience!

A miscarriage.

Appendicitis was probably the illness that had the highest likelihood of resulting in my death.

Monosomething. No, wait. When I was born a had a small hole in my heart, and they had to operate...which is worse?

a broken ankle

What kind of survey is this?

I had rubella / german measles when I was an infant. I don't remember it, but I've never had anything worse.

I've had scarlet fever and chicken pox (not simultaneously). I think the chicken pox were worse.

I had appendicitis....i hope i spelled it right :)

pneumonia

Hyperthyroidism. I weighed 95 pounds by the time it was treated, and I've never been so thin, so hungry all the time, so jittery, so emotional in my life. It's easy to treat, but a horror to live through.

The worst illness that I have had is asthma, followed by PMS

The worst illness that I have suffered because of is the illness that two of my close friends have - HIV/AIDS. I'd much rather experience my own asthma than the realization that they will very likely have long and painful deaths that I can't do a thing about except support them through it. And I cry a lot thinking about how I will likely lose them in a few years. I want them to be around forever. And these next few weeks I am staying away from them because another friend of mine has a contagious illness and I don't want to take even the slightest risk that I might transmit it to them if we hang out, because their immune systems aren't so good at fighting these things off as ours are. And I miss them so much...

I had food poisoning (salmonella) for 5 weeks, which became a systemic infection and spread to my legs. It was awful.

Hmmm... I guess this doesn't count injuries.. so I'd have to say a severe recurring bladder/kidney infection throughout my entire childhood.

something unknown but i was sick for about 3 weeks, and was frightened because no one knew what was wrong!

Poison Ivy.

Bi-Polar disorder, gall bladder disease

Chicken Pox.

Pneumonia.

When I was in college, I had gotten mono. I was eventually taken to the hospital with a fever of 106.2*F and rising. It really sucked.

collapsed lung

A deep depression that lasted somewhere over 7 months...that was my biggest illness

Depression

post traumatic stress disorder

Skin cancer
