Yep, you're allowed to vent. It's very aggro making when you want to play and can't due to things out of your control.
Re: internet connectivity problems: I really hate it when people say this to me but Have you tried unplugging your modem, waiting for ten secs and plugging it back in, making it go through a hard reboot? They get balky and need a hard reset sometimes.
If the modem reboot doesn't help, I second the suggestion to dig out some other hobbies and activities you've set aside or neglected. Do you write outside of The Sims? Are you a reader? Have a sewing project you can work on? Drawing, painting, music? Yoga or tai chi? Do you play any other computer games that do not require an internet connection? Puzzles or solitaire using a real deck of cards. Start a garden in pots or your back yard? Sort out that one closet, yeah, that one, with who knows what lurking way back in there? ;) Do you have some friends you can ring up and chat with?
