Yes, a human must find the balance between independence and collectivism to live a better life

Try not to be 100% independent because the stress can eat you alive. Also, try not to push people away that only wish to help. Try to find people you can lean on. I know it can be difficult considering your upbringing, but when things go bad, you can turn to that person and ask for help or just share feelings.

No. It's good to be independent.

But it's nice to have someone to lean on.

Takes a load off.

Kudos to you for taking care of your brother and yourself.
