Frequently when a person is physically ill or sustains an injury, he has an enforced solitude. For many people, this loneliness causes more suffering than the actual pain of the illness or injury.
If, however, such a person will utilize his time properly, he will be able to gain much from the experience. He can spend his time studying things he had never previously found the time to study (especially listening to cassette tapes). He can build up a close relationship with one or a few people, that he would not have been able to had he not been incapacitated. Or he can try to utilize the phone for charitable work.
The crucial factor is your attitude. Despair over loneliness will increase the suffering. Looking at the time available as a precious gift will decrease it.
