I would agree that catharsis is really just a way to treat the symptom, not the problem. But if it works in the short term and provides enough relief to work on the bigger issues, then I'd think that's a positive.

As for not having time to yourself - This sounds like something you can potentially control. If you have too many things on your plate, you might consider throttling back on one of them or giving it up temporarily. And certainly there's no reason to feel bad about needing time away from your bf. I love my wife and baby daughter very much, but I still need time alone to take care of myself. It's not something to feel guilty about. It's perfectly normal to want some time alone, even if it's just to go shopping. Funny, some of my best alone time is spent watching a TV show on my iPod while I'm holding my daughter and she's fallen asleep. I'm not physically alone, but my mind is elsewhere for 30 mins or so at least.
