What is a word for someone who prefers to be lonely? [closed]

A word that means someone isn't a people's person, someone who feels much more comfortable without the need of friends or family and keeps to themselves.

Example: I have a talent in music and drawing. There's tons of instrumentals I want to put words to. I'm also trying to hone my skills to draw free-handed which will take a significant amount of time. And as if the dozens of anime series I haven't finished watching wasn't bad enough; in addition there are a great number of other TV shows that I want to catch up on. I don't have the time for nor the inclination to lead a busy social life.

In short, "I'm sort of a ________. You could say, I've got too much on my plate".

A loner (noun):

A person that prefers not to associate with others

'my interest in birdwatching had made me a bit of a loner'

self-contained (adj.):

(Of a person) quiet and independent; not depending on or influenced by others

'I can look after myself better than most people; I'm self contained.'

I suggest the word recluse defined by Oxford dictionary as:

recluse (noun)

A person who lives a solitary life and tends to avoid other people.

'He seems to be somewhat of a recluse, he rarely goes out on the weekends and tends to shy away from new people.'
