Al, thanks for your honesty. What’s the simplest explanation I can give?
Our thoughts and emotions are all governed by chemical/electrical reactions within the brain. In healthy people, it is as you say - individual exert an enormous amount of power over their state of mind. However, in some individuals there is a fundamental underlying problem with the chemical/electrical reactions. The chemicals known as neurotransmitters simply do not function as well as they should, and, as a result, that person has an altered mood.
Saying “altered mood” doesn’t really convey the intensity. Imagine being wrapped in a glass cocoon. It is tight enough that just breathing aches. You can see and hear other people around you getting on with their lives, but it is all filtered through the glass so that it’s like watching a very weak television signal - all the good emotion stripped out. Doing anything, participating in any activity becomes, not relaxation, but something that requires all your strength and leaves you so exhausted, you can’t press outward against the cocoon anymore, and it contracts, causing more pain.
Against all logic, all reassurance from friends, all evidence from past and current relationships, you feel worthless. The cocoon becomes a black hole, and you absorb everything good given to you without feeling any better or being able to give anything back. You are a parasite, a burden, a millstone to every person who cares about you.
Between that and the constant physical, emotional, mental, and spiritual anguish, it’s no surprise many people with depression begin to think about killing themselves. It’s not an act of selfishness. It’s a manifestation of the same chemical imbalance in the brain that causes the other symptoms. It’s a desperate attempt to escape pain and to relieve the ones we love of the burden we cause.
To those on the outside, it’s beyond frustrating. You begin to feel worthless, because nothing you do to help your friend makes a difference. You resent your friend, because they don’t even seem to be trying. What you’re missing is that they are trying. They’re just held down by thousand pound chains.
I’ve experienced bouts of depression since I was eleven years old. They have varied from a six-week long period of ennui and fatigue to nearly two years of talking, taking pills, sitting in sunlight, exercising, gardening, sleeping, reading, and calling friends late at night so I could hear another human voice and push away the impulse to carve chunks of flesh out of my body with a knife.
I’ve learned in the past few years that while medication can help, it is only a small part of answer. When depressed, I crave sunlight. If I eat anything containing wheat, within 48 hours, I will have suicidal impulses. I sleep 10+ hours a night and still crave a nap in the mid day. I want more than anything to feel human touch - a hug, holding hands, snuggling with someone, getting a backrub. Exercise helps enormously, but it is one of the most difficult things to do in the middle of a depressive episode. Talk therapy helps, but it’s expensive as hell, and much depends on the therapist you find.
Does that help, Al?
