Hi Rembrant and welcome back:) I have had the strange, weak hand sensation before as well. I did as a precaution however, see my doctor to rule out anything physcially wrong. If you have not been to a regular MD for a check-up recently, I would suggest setting up an appointment. You may also want to rule out that this is not a side effect of your medication, as they can vary
If however, you have been checked out, and this does seem to be from anxiety, then you will want to keep working on bringing down your overall stress levels. Practice your coping mechanisms such as breathing and relaxation exercises, meditation, a regular exercise regime, ect.
You might want to look up this site. It has the most comprehensive list of anxiety symptoms I have seen. (also look into the aforementioned things as well. Here is the site:

I am glad that you feel comfortable coming back here:) I hope that you will continue to do so, and keep working on your recovery!
Take care,
