Hi Erin,
Yes, depression is linked to illness (especially for us, UC is not one of those flashy, sexy diseases that you can talk about around the coffee table with friends...ours is a 'hide it in the closet' type of disease that makes matters so much worse morally and emotionally...having to hide both our pain and our embarrassment)...not being able to control your body, especially our bowels, our output is terrifying. Having had it 'fixed' with a pouch only to discover that nothing is ever really fixed but just 'adjusted to a new normal' makes it worse.
I consider each setback, blockage and occlusion a major insult to my independence. I am too active and alive to accept them as normal especially since they pop up out of the blue, throw my whole body into shut-down and leave me weeping in pain and misery...that in itself is depressing enough but add to that that it is not a one-time thing but a lifestyle and you have every reason to be depressed.
I have some useful fixes for my mood, most of them involve exercise, sports, taking back control of what I can, long walks (fine, long limps, lately), hysterical laughter on the phone with my best friend, absurd movies, sad music (very cathartic to get those 'good tears' flowing and getting the anxiety out) and good meals with friends and family.
I fight my depression anyway that I can, mostly by not allowing it to set in for too long...a good cry yes, a week in bed? No. Mind you, ice cream, chocolate, cake etc go a long way into helping me through some hard days...
Find what helps you and use it for all it is worth...dance til you drop, sing at the top of your lungs, scream, cry, yell at the Gods, but do not keep 'the sad' inside...let it out. The more 'out' it is the less sad you feel...Especially if this is situational depression and not clinical depression (may need meds for that one).
