At times I can seem rather aloof and very cold emotionally.

It's nothing to fear though. I am after all, without proper diagnosis, a schizoid.

A schizoid is defined as having most of the following:

1. neither desires nor enjoys close relationships, including being part of a family
2. almost always chooses solitary activities
3. has little, if any, interest in having sexual experiences with another person
4. takes pleasure in few, if any, activities
5. lacks close friends or confidants other than first-degree relatives
6. appears indifferent to the praise or criticism of others
7. shows emotional coldness, detachment, or flattened affect

Generally it's difficult to really say if I fully have this disorder as it seems to come and go but I will say that after reading the profile it's possible that I do the best I can ignore these symptoms and lead a life that is free of complete solitude.
