"Lonely."

Lonely.
If you get to obsessed with something--or more specifically, someone--then it's hard to be away from them. Even for a littly while. You'll feel this sense of being deserted and being lonely, but all that really means is in truth you are perfectly happy. You know you take your alone time...so what's wrong with them taking their's? You shouldn't fell offended. It's just human nature. It's hard being alone, not talking, but it's a perfect time to remember to yourself, or your friends.
