Abt digital camera canon power shot A250

When I turn my camera on my starting screen will appear and it will stay on for only 30 seconds and then turn itself back off. The shutter does not move. I think it is jammed. I dropped my purse and the camera was inside of it. I think it may have been the cause of my problems. Im not sure what the correct term is but the part of the camera that sticks out in the front to help focus and get close does not move either. It is slightly out like is is jammed as well... please help I love this camera!
