Can a person drive a car after a foot amputation?

Yes. There are cars which are outfitted for handicapped people which allows even amputees to drive.
Eventually yes... Initially it is not recommended as you will probably have a bulky bandage and you will be using a surgical shoe or boot of some sort. You will need to plan to have someone drive you around until your doctor feels that it is safe for you to drive on your own.
Yes. The ability to drive a car in a normal configuration can be done as long as there is a part of the foot that can reliably be used to work the peddles. In the event that this is not the case then the car can be configured for hand controls.

Yes. It is not uncommon for depression following any removal of part of your body such as a leg, foot, breast, or arm. Talk with your doctor about support groups in your area and medications that can help.
AMPUTATION SUPPORT. I know some hospitals sponsor "Amputation Support Groups", where patients can talk to each other about their feelings regarding their amputation. Sometimes a psychiatrist or psychologist is involved. You should also mention this to your primary physician.

Will I be able to run after a foot amputation?

Yes. It depends on your strength and conditioning and the level of amputation. Most people can perform all daily activities and enjoy a regular excercize routine.
Possibly. Younger/ healthier patients are able to do almost everything after an amputation, including running. The higher the level of the amputation, the more work on the heart to exercise, and the more difficult to learn to walk. Most people can learn to walk after a below knee amputation. Many amputees play sports, including skiing, running, etc.
Possibly. If you were able to run before the surgery, after a period of rehabilitation you may be able to return to running following the surgery.
Possible. There are prosthetic devices available for runners of all levels. It is recommended that patients get used to a walking prosthesis before obtaining a running leg. If the ankle/heel are still present there are devices that can be used to "extend" the foot and provide some of the bounce necessary for running.
