I get like that alot too. I just have to go somewhere. Usually outside somewhere wuiet and just kick ym feet up and close my eyes and just soak in all the sounds around me. Just stay in the moment. I know you said noise is bothering you. But for me to just listen to my breathing, the birds, whatever and just feel the sun on my body and the breeze blowing. Just everything in that moment helps me so much.
I hope you feel better.
