Rest Cure treatment was popular during the 19th century, and it was tried on women who had hysteria.

In Genesis, God created a companion for Adam. We were not meant to be entirely alone.
When you see that your grief is leading into a sin of worry, fear, self-pity, hypersensitivity, insensitivity, you need to reach out to friends for prayer.
But if we walk in the light as He is in the light, we have fellowship with one another, and the blood of Jesus Christ His Son cleanses us from all sin. 1 John 1:7 NKJV
Confess your trespasses to one another, and pray for one another, that you may be healed. The effective, fervent prayer of a righteous man avails much. James 5:16 NKJV
