Sérgio, I presume it is indeed yourself, not a friend, who has been spurned in love. I am sorry to hear it. But I think shutting yourself in a cave for six months is a rather extreme reaction. However, the good news is that when you come out, you will be in daylight, unless your watch tells sidereal time. This is because, the 24 hour day includes the time it takes for the earth to spin on its axis once relative to the fixed stars (about 23 hrs 56 mins) plus the time it takes, on average, for the sun to be again overhead the same meridian (about 4 mins).
So, after 182 'days' you would emerge to find it is exactly the same time of day as when you went in, give or take only the correction for the infamous Equation of Time. So, you might find it up to about half an hour out. But I do hope you will be able to reconsider your plight and find some more profitable way to overcome your grief.
