Wow, once a week?! My mom would be over the moon. We talk every couple months or so. Sometimes I call, sometimes she calls. Every once in awhile, we'll email something back and forth.
But really, we're not close. She was pretty neglectful growing up, and doesn't really get that, so I don't tend to feel close. I also tend to feel worse the more time I spend interacting with her, so I have to keep that to a minimum for my own sanity and health. Email is better. Calls tend to be 20 minutes to an hour.
My whole family is also very disconnected. I love my sister, but only talk to her every other month or so (I'd love to talk more, she doesn't return my calls). I only talk to my dad on birthdays and major holidays, and he never calls me. Last year he moved and changed his phone number, and didn't bother telling me or my sister. He hasn't talked to my brother in probably ~8 years. My sister and brother don't talk. My brother is recovering from addiction and just recently out of jail, so I try to keep up with him to be supportive, but he's terrible about calling me back too, so again, we only talk every couple of months it seems like.

And I don't think my therapist gets why I feel miserable and like I'm all alone in the world. *Sigh*.
