Hi and welcome, Samij!
Yes, if you have fibromyalgia, it can surely be a rough ride; much like a roller-coaster, at least for me.
A key thing is to pace yourself--don't overdo, but don't settle for sitting or lying down a lot, either. Movement does help. I sort of play it by ear as far as how much walking and how active I can be on any given day. Some days I can get a lot done; and sometimes even the next day is pretty pathetic!
Little goals can help. Even if you're only able to do just a little bit of a project, pat yourself on the back. If we try to see the positive things in our lives, it's not "Pollyannaish," it's just a reminder to ourselves that we do have good moments, even while dealing with other issues.
This forum has been very helpful to me, as far as how to get by having fibro. "Tons" of info in past posts, and the people here are great and supportive.
Having a strong faith helps me, personally, and it's my backbone. I also like to do hobbies as I can find time for, and go for short walks. Having a little something to look forward to helps, too, and it can be something small, such as a quick trip to a craft store, a simple picnic, mini visit to a friend, or anything.
Could your meds be making you tired? Mine do! My doctor prescribed Neurontin (gabapentin) in 100mg capsules, so it's more bearable for me. I also take Flexeril, and sometimes take only a half or quarter of a tablet, just to take the edge off.
I hope you'll be patient with yourself. It takes time to navigate fibro, for sure! Take baby steps to get to those small goals.
Could your children help with household chores? Or someone from your church, or a close relative?
I still have my dreams, and I'm trying to achieve them, inch by inch. Some days it seems frustrating, but then again tomorrow is another day! Just do a little each day towards your goals.
You're not worthless! You sound like a wonderful, concerned and caring person who is dealing with frustration. That's okay. We all need to take our steps to solve our issues and get our lives back.
Yes, fibro is a roller-coaster ride! There are definitely hills and valleys, but I've found life is still good, and while I can no longer do some of the things I used to do, I'm swapping with what I can do, and just seeing how each day goes.
Best wishes and prayers. Check out Fibro 101, the very first thread on this forum. Great info! Hope you keep posting and let us know how things are going.
P.S. A heating pad, using topical creams (try just a little at first), dry skin brushing, and gentle massage all help me, personally. As I said earlier, lots of ideas here--just use the search box above.
