Windows and waves

When do these windows and waves leave.  I had no anxiety or not much for a few months and the panic came back a few nights ago.  I have alternating good nights of sleep with insomnia.  Tonight I am Stressed out as I need a job and having health anxiety about my infection, cold  and back.  It seems like i am never going to get better.  I can't sleep and have sheer exhaustion from the cold and it is 1015.  I keep coughing.
