First, you’re stronger than i. Congrats on the life shift.
Second, “not having constant input” can be viewed as a skill. Meditation is a way that I have practiced that skill (I’m quite out of practice these days).
I recommend doing guided meditation. It’s not the thing for everyone, but it helps some.
X2go is the successor to NX and works well IMO, though I’ve never tried Rustdesk to compare.
