Here is just a brief outline of the resources available to you, when you are challenged with a physical illness. A few that I know are listed at the bottom of this page. Sometimes oil is used to symbolize an anointing for healing. You can also prayer for any others with illnesses. The more we focus on helping others, the more God can work in our own lives.
Praise is also a form of prayer.
Since God inhabits the praises of His people, Christ's very presence will be with you. Following the unction of the Holy Spirit will help you decide which ones to use. Sometimes they allow you to feel validated, although I generally recommend that you spend the majority of your time with people who are healthy or who focus more on positive things. Some people simply use the name of Jesus, in any way you are led. I would sing praise songs, during times of great distress.
