Learning curve on the 7D coming from the 20d lol

Ok you have helped me pick the type of new camera I want, (I think the 7D) but coming from the 20D I am a bit worried about this learning curve. I mean it is going to be to hard for me to get used to?

As you can see I am one of those that hold on to their cameras so this choice of camera needs to last for me. I don't have mega bucks to spend on cameras. So I really studied the cameras. I was going to get a 5D mark ll but was told my 10-22 lens would not work on it and I LOVE THAT lens. I was also told here that I need MORE expensive glass then what I have and use so that did it for me NO 5D Mark ll. So you led me to the 60D or 7D. I think I would like the 7D more but really FEAR the learning curve. Heck I was just getting used to my 20d lol.

I have been caring for my mother who passed away for years now and haven't been able to go shoot but now I can and wanted a more MP camera (simply for cropping). My favorite lens is the 70-300 is, with a second to the 10-22. I also own
100 macro
400mm 5.6
50 mm 1.8
60 mm macro

Now I need to know if I can handle this learning curve of the 7D. I know it's kind of hard for you to tell me that but maybe you can tell me just how hard this is going to be lol.
Thanks Cheryl
