Most of the time, people take pictures of only the good times. You look at a photo album and rarely see sad tears, a difficult moment, etc....
There has been this trend of taking photos during hard times just to prove that a person is getting through the hard times - fighting through them!!
I have done this over the last 14 years - and when I was younger and taking pictures in the hospital and what not, people told me I was crazy and asked me why I would want to remember such awful moments.
I am big on filing and documenting experiences. To add to that, I find that taking pictures of hard moments makes me remember what I have been able to cope with, what I have been able to handle in the past. When I am going through a rough time, I can always look at these pictures and remember that it has been worse and I've come out the other side just fine. And on the flip side - there are pictures of hard moments during really great experiences. This isn't to remind me that things were still crappy. This is to remind me that even though I was going through hell, I was still able to enjoy myself.
For instance, this picture is when I was on a cruise in the Mediterranean. It was my first trip to Europe and I had the nerve to go by myself. It was one of the greatest things that I have ever done, one of the best trips I ever had, and to top it off, I managed to do it when I was still sick - which, for me, feels like a huge accomplishment. I was doing a Methotrexate injection on the cruise ship.
This next picture is of simply getting bloodwork done. This is what my day looks like at least once a month. Why did I take a picture? Well for one, people may not believe me when I tell them... Two, it's a little incredulous... Three, it's a quick reminder of how much I need to be monitored and why I need to be paying attention to all of my medical stuff.
This next one is of my hospital bracelets for a standard pouchoscopy (colonoscopy without the colon) ... I always find it entertaining to watch a nurse try and fit all of my medication allergies onto the one red bracelet. 
The next photo is when I am getting ready for a simple x-ray. I always have time to kill waiting for appointments, and frankly this was probably the most flattering hospital 'gown' I've ever had to wear.
Oh, also, there was some 'disbelief' going on about how many appointments that I have. Sometimes people think that I am exaggerating the amount of appointments that I go to and the testing that I get done.
I assure you - it's no exaggeration. The last specialist to look at my Netcare chart was absolutely shocked at how much blood they've taken and how many tests they have done (finally) to try and figure this all out.
It also shows that no matter how bad things get - I still find a reason to smile.
