So
Last summer something happened, i'm unsure of what it was exactly but i just felt so… horrible? Like one day It just happened, i don't know how to describe the feeling but it was very intense in a way i've never felt before, most of the day i would just sit in my bed and feel absolutely awful, to the point where it felt completely unbearable. I basically never left my room except for when it was time to eat and then i had barely any appetite, but i forced myself to eat and behave normal enough.
After a week or so (I'm not entirely sure) it gradually stopped and i was back to normal again.

So any idea on why this happened? I wish i knew because i'm scared of it happening again
