I hope everything starts going better and you can figure out what's going on. Please keep us posted, my husband is 29 and is having basically the same symptoms as you described, he's the same way with going to the doctor but I have put my foot down!!! He's going to the doctor TOMARROW!!! Christmas night he said he thought he actually had a heart attack, I never know whats going on because he hides from me or just says he's tired or cant sleep or whatever. We have 5 kids and I dont want to explain to them why he's not gonna be around no more if he keeps this up.
Take care
