Some things that helped my hubby through it:
Prayer--serenity prayer is awesome
Faith---"If you have faith as small as a mustard seed, you can say to this mulberry tree, 'Be uprooted and planted in the sea' and it will obey you." Luke 17:6
Wisdom--Learn every thing you can about the disease
Support -- lchelp is a great start, talk to other family memebers affected, caregivers
LIVE ONE DAY AT A TIME---Remember, "Yesterday was the past, tomorrow is the the future and today is a gift, that's why it is called the present."
Networking--get the whole family involved in the support and healing. (including friends, church,acquaintenances that want to help).
Surround yourself and your boyfriend with positive emotions---mediatation, calming music, reading the Bible.
Remember that life is not over with a diagnosis, a new life is just beginning.
Hope this helps.
Good Luck and God BLess!!
My prayers are with you!!
