Get this overwhelming preasure in head, just from loud noises and people saying hello

Can anyone relate. When a stranger says hello or even when someone just walks past me I'll get this crazy headache in my temples like my veins are throbbing This feeling will last for most of the day! Like someones squeezing my head. I have this almost constant daily. Then this overwhelming feeling of desolation, demoralised feeling kicks in, then triggering my depression. I dissassociate then feel like im not on this plane. These are not like normal headaches its literally head pain! Its weird and it seems anything can trigger it!
