I am sorry to hear of all your bad news. Stress is indeed a cause of many illnesses and you have to acknowledge and treat it.
The prevailing thoughts seem to point to medications for stress and depression.
However, there is a better way. Seek out those in your life who are your spiritual leaders and teachers (pastors, Sunday school teachers, friends). Talk with them about these issues. I believe that there is a spiritual battle that we cannot see. The Devil is very cunning in using many things to wear you down. He wears you down physically and emotionally first, and then gets you spiritually. Keep in mind that Jesus has already conquered the Devil and is ready to help you. All you have to do is to reach out to Him and claim that victory. You can do all things in Christ, who strengthens you. Pray to Him for peace and guidance and you can get through all of this. Don't let the Devil discourage you.
God bless and thank you.
I will pray for you.
I don't know if you have cable or not; but there is a show called Way of the Master that is very good and encouraging. Also on the radio, I enjoy listening to the late Dr. AdrXXXXX XXXXX. He is such a blessing.
Til next time :)
