I’m mentallly struggling as well OP as my Dad has terminal cancer so am not allowed to see him.
As he’s menatally checked out i’m getting no sense or anything more than a minutes phone conversation out of him. I would go and see him but have no idea if its days, weeks or months that he has to live
I know the situatons are different but my way of (barely) dealing with it is firstly to try and keep my body clock to as normal as possible, make a list of all the jobs that need doing around the house and tackle one each day (this week i’m on a deep clean/de clutter of a room at a time), listen to one new album a day and watch something I wouldn’t normally, also staying well away from alcohol. I’m also doing 100 press/sit/pull ups a day and marking it off
Theres still a massive time void but can be filled with a walk/run/cycle or going to the shops (I’m like an old woman now and have found I end up talking to strangers a lot :D on my trips)
