Sometimes the only way to mental peace is to take a step back and let the world pass on you, that's the only way to let go of toxic people, one-sided relationships, and the people who do nothing but exploit you in their needs. That's the only way to find out who reaches to you and lend a hand to move forward together.
Always being there is righteous no doubt and it also gives you peace of mind in one way but trading it for your self-dignity and self-worth will never have any charm in the long term.
And don't worry if no one reaches out to you, it's always better to cut the stretched ropes before someone else cut them and they leap back to hurt you.
But in doing so do not ever lose your character and your conscience, because it's better to be alone than losing yourself while finding someone to hold hands. How will you devote yourself to someone else if you don't even recognize yourself?
