Hi @nightwing81
Understandable that your mum's health problems would give rise to worry for you. Your own changing living circumstances could also understandably be bringing up fears, especially if you feel you have been in the same pattern for a long time.
I admit I often need to go to bed when too overwhelmed. It seems my nervous system needs a reset fairly frequently, to help calm down my overly excitable nerves. Even a short nap, or just a rest, can help me calm down. This might not be a bad idea on occasions, except I also go through periods of sleeping way too much by far.
There are other things that may be wiser: breath meditation for example (focusing on the breath, slowing it and deepening it). Even five minutes of that helps me sometimes, better if longer. Physical activities are good, of course. For me it might be walking in nature.
