It depends entirely on the person. I had a similar thing happen to me, except that I managed to get a single my first couple years of school. But I know from others, that it often creates a very intimate, fraternal bond which gives kids some semblance of a family bond before they are able to get a real social life, join clubs, make friends, find a partner etc.
