Is this Fibromyalgia? What are your stories, symptoms, how did it come about in your life?

I'm a 27 year old girl who got married 3 years ago and the stress began. HUGE stresses. Got married, bad inlaw problems, pregnant right off the bat, mom had heart surgery and neck surgery, etc. I thought that mentally I handled it okay. I've always had anxiety but I seemed to get through it okay. I started having ovarian pain which led me on an ENDLESS search to find out what it was. Diagosis: "Probably adhesions". Then I had a swollen inguinal lymph node that was painful at first, well I worried so much about it and touched it so much that I had to have it removed for biopsy. Biopsy was normal, thank GOD. Now I'm having neck pain, the way I would describe it is not in my bones but in my muscles or nerves. My boobs feel sensitive. My ribcage is easily irritated. I always feel like I have something weird underneath my arms or something. Now, I'm an emotional mess. I've had a ultrasounds/catscans, bloodtests for ovarian and bowel cancer, CBC w/diff, now it's my neck that's bothering me.
I've become depressed, I've never been this way before. I'm overly anxious and overly concentrated on my body. I'm very "aware" of all of the sensations on my body. I'm tired all of the time. I don't sleep well, hence Ambien, Tylenol PM, I've tried it all. I'm going to a chiropractor now for my neck to see if they can help me. I'm throwing money down the money pit…and have been for 3 years. I'm feeling like either I'm a hypochondriac and imagining all of this or maybe I have fibro. I recently have been reading about it and some of it makes sense, I'm pretty young though? They have tried me on Flexeril for my neck which didn't help. Xrays showed nothing. I guess I will seek out an MRI. The weird sensations in my boobs, around my ribcage, and arm pits, in addition to my neck, and chronic pelvic pain….make me think maybe it's fibro. I can't remember a day that I felt GOOD and energetic. I'm not obese, I only weigh 118lbs and I'm 5'6". I just started Cymbalta.
How come taking a xanax makes these pains and weird sensations go away. I currently don't have any and I am not using any but how come it makes it go away….but do not mistake….these pains ARE REAL and NOT IN MY HEAD. I SWEAR. Now, because I've had "so many things" hurt or go wrong with me, I feel like my family doesn't take me seriously and I feel embarrassed. What do you think? Care to share your stories of Fibro? Just to soothe my little soul for a while? Anything would help right now, I'm just so frustrated. :(….and scared. 🙁
