Yes ain Sofia, chronic pain does something to the brain making it difficult to think of anything else. It can consume us. That coupled with crap on the internet telling us fibromyalgia never gets better. That is crap!!! They may not have a cure right now, but there are many things you can do to make it manageable. (I do believe that fibro may have different causes for each of us this is why we all respond differently) finding what works best for you is the key. I know it's hard but rather then thinking about where you are today, try to find clues that will improve your condition. You are in a battle right now, some days you must rest and heal other days you must fight. Your not living for today, you are fighting for the life you want tomorrow. It is a "time" of your life, not your future.
You did not share what you have tried medically for your fibro. But I can tell u if u just started a medication, most take time to start really working, some will never work for u and you have to move to the next until you find the right one. Vitamen D and magnissium seem to be the most helpful supplements and tend to improve almost all sufferers. But you must find what works for u.
I'm guessing by your post your not getting good sleep, fibro affects your muscles and the brain is a muscle. It needs good sleep to recover. If this is your case please talk to your doctor about getting that under control.
I have been there. I have a post in "moan and complain" that was written when I had gone from begging God to help me to begging him to come get me to thinking maybe there was no God and suicide wouldn't be the one unforgivable sin. He sustained me. I don't know how I made through, it had to be by his grace because I've never been afraid of death, my family would be better off (I had become a complete burden) my son was taking advantage of my condition and bullying me and I had given up on getting any better.
Things have gotten WAY better. I also have a post stating "I played ball with my dog". I hope you will read them as it might give you that glimps of light that I so desperately needed.
You can message me if you need to. Many on this site understand what you are feeling, Some are in the same state of mind but even more have been where you are.
You are in my thoughts and prayers. I can only send you a virtual hug, but feel some arms wrapped gently around you and know you are going to be OK. I wish I could do more.
