My horror story narrative

Henry is a teen studying at college. He's a fairly ordinary teenager, no trouble at home and no trouble at college. Henry has loads of friends all with diverse backgrounds and interests. They used to all hang out together through their childhood from pre-school through to high-school, always meeting up getting up to no good having a laugh, but this all seemed to go wrong somehow when he started college...

Although Henry had loads of mates, they were growing up and their diverse backgrounds and interests drove them apart. Henry noticed this and it didn't sit well with him; he couldn't get his head round the concept of social clicks and how different his friends were becoming. Henry himself became a bit of a drifter; he had no particular social click or 'best mates', and just drifted from one group of friends to the other, adapting to the personalities and attitudes of the people within the groups, and for a while this is ok, but after several months of switching personalities several times a day and not really being 'himself', Henry begins to develop a psychitzophrenic state of mind. He's unable to identify his real self and ends up switching in an instant between the personalities he has developed. These changes in his mind end up driving Henry mad and he flips out randomly, becoming unpredictably aggressive towards unpredictable people and the next second he'll be his 'normal' self; calm, kind and ambitious. He starts to tear into the groups of friends, accusing them of 'destroying' him.

By now Henry's mind is in a complete state of flux; he doesn't know who he is, who he wants to be, who his friends are or even what music he likes. Who knows what he'll do...
