I think u can ask the HR for earlier termination. Tell them
about how u feel. It's normal to terminate early. The contract is
not so strict and binding, as long as both parties agree, there's
no problem........Find someone who can make the decision while ur
manager is away. (to terminate early).
If u cant find someone who can decide, then contact ur manager or
wait for him. Ask for early termination.....
Remember to emphasize ur 'burned-out/ stressed out/ unhappy/ can't
continue any more' situation while talking to HR or ur manager.
They're unlikely to ask u to continue.......Probably u can stop
working on that same day or the next day.....
But if u r really required to serve the 2 weeks, then just do
it.....Don't stress urself in the 2 weeks time, take it easy....In
the meantime, don't worry about making mistakes or missing
deadlines, like u used to worry. Just work as usual and everything
will be ok. Basically u know the ropes already. Be more confident.
Cruise for 2 weeks.
And let everybody know u r leaving. They will start to put less
pressure on u, expect less from u, and maybe assign some of ur
tasks to other people. All this will help to reduce ur
stress.
And don't worry abt ur BF......explain u r stressed out. He won't
think less of u or be disappointed with u. Get a better job and
impress him.
And more importantly.....u know u should really consider a job
carefully from now on.
