Leslie Cheung for example. His brain is wired differently. He didnt know. He was confused why he didnt have the expected happiness when he already has everything. He wont kill himself if he understand his own inability to be happy is biological.

Commit suicide = coward
Living on = courage

Look into how to solve your dog issues, slowly. Ask for help. Just type anything.

Like i said. I met few ppl that just be depressed no matter what.

The latest is friend's boss. Married, beautiful wife, children all normal no disability. Rich as fuck. Business also all okay, conlanfirm wont fail. Already open 6 branches.

The only drawback is parents growing old. Started hospital visit. That guy hang himself suddenly. Apparently last depression episode is back in university. No ppl realize he battling depression although life seems doing well.

I am telling u. Its somwthing in the brain. They are in depressive mode by default. Their main problem is the world keep pressuring them to be happy like normal ppl, which they couldnt. So they stuck in this infinite loop of looking for happiness.

Taking on to care for another living being is not easy, dogs or humans. The responsibility to ensure their safety and wellbeing. Taking care of one's own need is a full time job own it's own, what more having to care for another.

That's why I don't judge when people give up their kids for adoption, I don't agree with it, but at times, some people might really not be up for it. Not saying it's the right thing, but it's the lesser of 2 evils, which I can't stand to judge, because I have not been in that shoe, and i hope i never have to.
