It just sucks. I don't really feel like doing something that I'm not interested in. I don't like faking either! But, I've heard "fake it till you make it"...maybe it'll work! I hope things are better with you, and if they are...I'm glad!
It's not that I'm doing things I'm not interested in. Stuff that I thought was "not my style" like martial arts and theatre wound up being GALing that I really enjoy.
In the past, a lot of things I didn't do b/c I was focused on my kids instead of me, or was maybe too scared to try new things. Now that I'm challening myself I've found a lot of these are enjoyable. If I didn't enjoy them, then I would keep trying new, different activities until I found something I did enjoy. There's so much out there. Volunteer work for example, doesn't sound like fun, but you wind up helping people, making friends. The more challenging stuff that you do, the more self-confident you get also.
