I stamp alone too - but I like it. I recently was together with several local stampers at an event at our library, and we did talk about getting together sometime which I think will be fun.
Are there any stamping/scrapping stores near you? I know of some that have tables set up and open time for people to just come in and work on their projects. That would be a good way to meet others who share your hobby. Even if you're a stamper and they're scrappers, you still have a lot in common and can enjoy each other's company.
I hope you and others find stamping companions!
