thanks for all responses....
this aloneness is partly just part of my human condition and is often noticeable. but also partly from an end of 7 year relationship. so that's part of my roller coaster. i think it will pass fairly quickly...just the normal grieving i would expect after such an event.
I feel bad because we've been through a lot. I feel scared because this is new ground; like i have no one to do things with (automatically--so I have to create my life more actively). i also feel scared because one of the chief reasons for breaking up is that I (AND HER) need to stay single and develope a foundation and find myself and all that. I feel lonely because that's what happens after a break up.
It's been a roller coaster today...but i'm feeling OK right now...
