Go online with him and have him read some material on it with you. It is a real disease but it is hard to explain. My husband had a very hard time understanding it and it took him a while but he did see I was not faking or being lazy. We have been married for 29 years. The is a spoon theory online which shows them how hard it really is for us. Look it up!!If you have a problem finding it let me know. Take care and try not to stress. it makes it worst.

I have had Fibro for over 20 years.I have noticed with friends and family or partner..that they may understand for short periods of times..but soon forget..( sometimes even within the hour of reminding them) it is impossible for someone to truly relate to all of Fibro's symptoms..that go on within a 24 hour period.For myself what I have learned that helped me is to have a room set up just for me.I can go into this room..and lay down..turn on my electric blanket ( which helps reduce pain ) turn on my peaceful music...or call a Fibro friend for support...it is very important to have your own room to be able to heal..or rest and relax..be stress free..and not have to put a smile on..when your in pain..or even have a conversation when you ready to just lay on the floor..It is up to us to take care of our self as much as possible..because healthy people really can not understand..much love your way gentle hugs to you..hope this helps..

his video helped my partner ..understand a little..maybe because it was a guy saying it..!!.. https://youtu.be/S3WGMyfSU6c

Ask him to think about the sickest he has ever been with the flu, an injury, or other illness that makes you think you are dying or wish you were. Then tell him that's how you feel everyday. If he cannot understand, he might not be the right person to share your life with. I hope and pray that you can communicate this to him and that together you can work through the challenges on both sides of the diagnosis!
