I think you can feel uninteresting because you are bored with yourself!
That's exactly how I feel today. I'm feeling poorly and am very busy with work, DP is coping with a very stressful situation at work and has retreated into silence, DVDs and books, one of my close relationships has gone haywire so I feel lost there and all in all I was so grumpy this morning that I made even myself cross.
So I did the Pollyanna thing and looked for the good stuff.
I agree about R4, you will definately find something to talk about on there.
Facebook is great for politics and groups that share your interests, at the moment for me that is, 10-10, Forests, spending cuts, Samhain and Thriftiness. Find something and comment, I have 'friends' all over the world who have liked my opinions and asked to be a tiny part of my life.
If you an get childcare, do take up a hobby or join a campaigning group, too, it's nice to get away from the children out of the house.
You are still you, a better, brighter, knows lots more now, you. Go on, there's lots of experiences waiting out there for you.
