Is it okay to push people away and isolate yourself when you just can’t deal anymore?

I think you have to set healthy boundaries for yourself. So know when it’s ok to be vulnerable and know when you have to step away and take some time out for yourself and your own needs.
But make sure you nurture yourself and you don’t neglect the people who care about you genuinely.
Those people who drain me I have chosen to see them less but I still be kind to them.
I just don’t apologise for putting my needs first.
