Gluten Free Me?

I try not to whine or complain and am generally a private person.  Those who know me personally may beg to differ, but really...it's how I feel, yet maybe not the persona I tend to display.  Don't correct me...I did say, bold, & underline the word "try". :)
That being said, my health has wavered for years; including heart issues, fatigue, increased anaphylactic allergic reactions to the most common foods, skin sensitivities, and more.  I've gone to the doctor, tests done, "normal results" return, and a pill is recommended.  I'm not big on meds & currently don't take any prescriptions.  I want answers, not a bandage.  I don't want a beta blocker, I want to know what is causing my rapid heart rate.
Finally it got to be too much.  I was fearful of eating, drinking, & was often getting sick.  I typed up my whole medical history as best as I could recall & went to see a doctor friend of mine on Friday.  There's no complete conclusion, but she believes it's gluten intolerance.  Tests were taken and I am waiting the results.  After researching it, it makes sense & it would cause all my symptoms.  So I am trialing the gluten-free lifestyle.  With my husband supporting me, I'm hoping this journey ends in good results.
Back in the 80's, antibiotics were used, and used a lot, and  I was a sick kid who got them a lot. Those antibiotics reek havoc on the good flora in the intestine.  The small intestines cannot work when out of sync like this and inflammation starts - sometimes affecting many parts of the body.  I am not blaming anyone - this is why doctors "practice" medicine.  I just hate being the guinea pig.  Here's hoping that my new high fiber & protein diet with OTC probiotics aide in the healing process and I learn what its like to be normal again.
Have you ever spoken with someone who has been sick for a while and they finally find out the diagnosis, and while the diagnosis isn't the best, there's a sense of relief on their face in knowing what it is?  That's how I feel.  This isn't a "for sure" diagnosis, and I may not see results for months or more, but there's hope, and that's what I want at this point.
PS: Gluten is everywhere.  It's actually quite depressing.  But if it works, it's a lifestyle I'm willing to accept.
