I keep on having crazy feelings of detachment

As of late I keep on having crazy feelings of detachment with my own body and surroundings.

it usually occurs on my hand where my hands feel detached . As well as I have dryness and numbness on the left side of my tongue. SomTimes my heart starts racing fast .... and I have no clue why it happens it can happen at the most random of times. I was at a neurologist to rule out MS. And he said it's probably anxiety and panic attacks ... if you know of any treatment or skills to ease it please lMK thanks ,

I used to suffer from panic attacks wen I was younger

Does this happen right before you are stressed out?

It happens at the most random times!
