@heartathome i have not been closely following the conversation, so i'm not sure if this will support you rightly, but i hope so. i understand you have lost your inner rest because you worry about someone you love well being? And find it hard to deal with not knowing what is going?
i have suffered with this many times! It is so very hard for me to let go when i need to do that, the closer to the heart the more such inner unrest seems to be the case in my experience.
One way i deal with what i term to myself my 'emotional overload' is to acknowledge my inability to cope, without shame or guilt or taking on bad labels towards myself, or others of course. Also, and this is very important not trying to quell/resist the thoughts and feelings in our hearts but rather bring ourself is such a state into the presence of the Lord in prayer and ask Him to reveal how He deals with such sensitive situations.
i find that once the judging, character reducing turmoil and gossip, about the person i care about, as well as myself trying to deal with it rightly, is over, The Truth starts to become clear and what i term Jesus' will about my issue is revealed to me. Such happens always through the words of Scripture spoken from within your heart and mind. In the Spirit of love for God, myself and others. It is this Spirit i ask Jesus to dress me with, so i can enter Father's Heavenly Rest about this with the rest of myself where i already hsave learned to let go and trust Jesus with the welfare of those i love.
My faith in God's/Jesus' love, rather than the trouble my loved ones or i face doing the right thing is what gets me through these times. Yet i know it is not an easy Way out. But i also know it is the best Way to walk on. For once we have learned to trust Jesus with our whole heart about the issue we struggle with, we will certainly rule beside Him over our lives in the Heavenly Realms in that part of our lives, instead of sweating it down here in our often feeble, broken, and so very mortal inabilities.
At least it has always been like that for me when Jesus brought me His Victory dropping of my inabilities at His feet.
i hope this might be helpful. My prayers go out to you.

i know that finding God's Way of doing things, when it comes to dealing with our emotions and life situations, is unparalleled down on this earth.
