Flash emotions with memories?

i have anxiety problems and ive never noticed this before but last night was a very bad night for my anxiety and it took a very long time for me to sleep. and a few seconds ago i just hit the paste button because i was bored and it popped up as a link to a picture from last night which made me remember the anxiousness and that feeling returned extremely quickly and then faded..but even as writing this i can feel the anxiety climbing...the picture is of something completely irrelevant and doesnt have anything to do with the feelings. but when i first experienced the memory and then the flash emotion it was immediate? like the feeling was directly linked to the memory? usually when i remember things i can remember what i felt like but i dont feel like that at the time of remember? i can attest to anxiety breeding anxiety but can memories of anxiety breed anxiety? that seems to make sense right?
