You should NOT be embarrassed to say you had cancer. You should be PROUD to say you beat it! You're not weak, you're strong! As far as doctors go, if you have the right one, you'll actually like going to appointments. It took me years to find one I like and trust. He digs my car, so I love going for check ups so I can show him my latest mods.
I park by the back door so he can step outside after my appointment and listen to me start her up. The grin he gets makes it worthwhile!
