My dear "mentally weak" friend:
There was once I felt so despondent and emotionally stressed out, I msged a friend:

Sometimes the world pulls you from all directions
Stretching you thin
Yet expect you to be ok

He replied
You should learn to relax, think of someone you like
Listen to some songs…
It helps…

Feeling better, I said:
I guess every storm comes and passes.
I'll try to keep myself dry while it’s pouring
He then replied:
Well I guess you have to find a shelter then.
Home is the best shelter to keep you dry.

I think home is a 2 way concept.
It's your refuge,
But in turn,
You are your home's refuge too.
Stay strong
because you are much more than that.
