I worry n stress a lot even in small things so I drink n become aggressive. is there something wrong with me?

ok i was in a happy mood, went to the beach with my fren. had a nice time. clicked soem pictures uploaded on my facebook. was getting lots of likes from my mates and relatives. at the same time i was about to lose one of my jobs ( i work in 2 places). i was really worried n stressed. i went to a nearby pub n started to drink beer. may be 5 or 6 glasses n i came back home to check my facebook as i was eager to see the comments n likes on my bare chested pic in the water. one message was from my college fren. she said "wow nice n good to see u" i wasn't too happy with her as i was try to chat with her online but she always showed offline. but she sent me messages. it means that she had blocked my from online chatting. so i was really upset n wrote her that may be i should block her. she instantly replied "as u wish". that means she was online but hid herself. so i blocked her.
another like was from my causin sister. i was also upset with her that she had her likes comming i wrote something stupid n blocked her.
i blocked other two frens.
what's wrong with me?
