If you get depressed, doctors will prescribe you antidepressants which is drug that is supposed to lift your mood and "fix" depression (lol).
Imagine the following: Your life is not great and you're not where you want to be, as a result you get sad/depressed. If you take a pill that makes you feel good, you're felling good about something that generally YOU would fell bad about but know you fell ok/good about it. This is nasty part of antidepressants: Who are you?
Some people get depressed for chemical reasons and in that case antidepressants can make wonders for them. When you work long hours, don't exercise, don't care much about have a social life, eat poorly, etc. What do you get? Depression.
In this case you might have a chemical imbalance BUT it is because you're not taking care of yourself. If you take a antidepressant it will mess you up even more. If you become addict to it, you'll loose a sense of you own self because the pill affects your emotions. Some people think that pooping a pill solves everything.
So, by saying "ripping your soul", I mean that you're entering a hole that is really really hard to get out. I've faced depression, did some psychotherapy and I made the rational decision (thank God) of not taking any pills. I knew people who took them in a daily basis and it's not a happy picture at all. You've to switch meds every X years, people tend to feel sorry about themselves, etc etc. Those people I know are completely fucked up, in the next 10/20 years they'll become zombies most likely.
In my opinion, sometimes people have a huge EGO that gets in the way of growing up and turn into pill to feed their mental picture of themselves and the world.
For me, depression was not nice but I took it as a wake up call. Throw psychotherapy I became aware of stuff that was bothering but I was not aware of it.
Unless you've some physical problem that brings depression, today's depression is a simple product of the Western capitalism, social media, etc. Sometimes you just have to face the your own problems and grow the hell up.
Throw pain, you grow.
