i'm sick physically and mentally

am i wrong for doing what i did?
i feel horrible and now people wont forgive me
maybe i'm better off on my own or maybe drowning myself
in a lake somewhere i dont know why im feeling like this
its only 8am i dont think i can make it through the day without passing out
i already feel weak
im having trouble breathing feels like someone is stepping on my lungs very lightly
am i dieing or is this covid?..
