These symptoms can be caused by trauma that happened in the long ago past. Your current life situation could actually be fine but you have symptoms of past trama.
Seen too many people running around making drastic changes in their lives in an attempt to feel happy but each change just brings more depression because it doesn't work.
"Just make a change in your life" is some feel good bullshit. It's not that simple.
Seriously though, compared to being depressed when you can't fix it because you don't have any idea that something is wrong, drugs are fucking amazing. The shitty part is people end up trapped now as the drugs can fuel the negativity which lead to the depression in the first place.
The common thread though is that a single dose of the drug offers long-lasting protection, weeks or months or years. It's not about chemically changing the brain day after day, it's about using neurochemicals to jolt the brain out of a rut. It's about occasionally kickstarting the brain back into normal self-regulation, not using externally supplied chemicals to permanently supplement dysregulation.
Completely depends on the drug, person and context.
The painkillers when I dislocated my shoulder and they had to reset it? Wonderful.
The antidepressants that after several weeks (so once they'd started "working properly"), made me feel "not unhappy" but like a robot and then also gave me vivid, real nightmares in which I died horribly over and over again? Not so great...
I'd never touch antidepressants ever again. For some people they do work, but for others they don't. Yet we still push them on everyone.
It's not even that they are lying, but we humans are very good at hiding truths, even from ourselves. It can be very hard to truly admit that one is unhappy about one's life, and frankly many people have never really experienced a true sense of fulfillment, peace, belonging, purpose and happiness, and don't know what it would feel like or understand how lacking the feeling is in their lives.
"My life is fine" generally means "I've checked the right boxes: 'success', 'friends', a relationship, but I still feel empty." Don't use drugs to numb that feeling. Listen to it.
