the man was swimming in his clothes..did he swim to the beach from somewhere?

To TDOC: Yes

To AITA: You are VERY VERY CLOSE

was he stuck somewhere and all he had to eat was seagull..or was somewith him named seagull and they died?

He forgot he didnt have any money ran out and got hit by a car.

Certain parts of your question are correct.
It is easier for me to answer you if you keep the questions simple (i.e Was he stuck somewhere?)

haha, no effing way.
this is class.
okay, so, the guy lost his mother/wife/best friend in the world...
aaaaand, he was swimming to lose weight?
no thats crap.
he was swimming because they died in the sea. OR IN A BOAT WRECK! oooh thats a good twist.
so there was an accident, & he lost someone, swam back to shore & ordered a meal [as you do when you lose someone], only to realise that ;
1. it was their favourite meal,
2. it was them, cooked into a soup,
3. seagul soup kills delusions somehow, the guy realises HE killed them, & goes to top himself too.

:)

Will I be dissapointed when I find out the answer is something lame like his chair had three legs?

well i think that he was stuck somewhere with his friend named seagull...they were there for quite awhile..andthey started fighting and the man killed the guy named seagull..and well stuck there with nothing to eat he ate his friend..but it was from somewhere that he would be on beach from
