I really like my solitude. I do. But I need regular contact with other people or I really start to not feel so great. Luckily I do have friends.
Alone is fine when that's what you need...but loneliness to me indicates a negative, unhealthy feeling, a need for contact, as opposed to just the state of being alone at a given point in time. So I don't think being lonely is good, especially since it's been linked to so many health problems.
I'm fine with being amongst my friends for the day now and then and then coming home to quiet solitude...but there's a lot of times I wish I had some female company. I've just never really had that, so naturally I miss it. And I do think there's something wrong with that if it makes me feel as bad as it sometimes does. So, that's why I'm trying to change it.
