For a long time I went through a heightened emotional state, where I felt much the same way you do - sadness, emptiness, despair, anxiety, etc. For me, the only thing that worked was medication. I knew if I wanted to survive a while longer my only option was to numb the pain. Doing so allowed me to feel unfazed, which, considering where I was at, was a big improvement in my eyes. That allowed me to just sit back and laugh at life a bit more, and waste my time by way of escapism and pointless media consumption. I couldn't have done this without the psych meds though - things were too raw and painful before I got started on them.
I know meds are generally poo poo'd on here, but if you want it all to stop going around in your head and get some sleep at night, they may be worth considering.
