Breakdown... Running out of days off.

I want to keep this brief so I can get to the point. I've got a family, a home, a dog and a career... and I am on the verge of a total breakdown. I lack any semblance of charisma, and I am completely non-confrontational unless you are threatening my family. I am often perceived as stupid by people who don't know me well, because I function so poorly in conferences and groups which does bother me... but people can think whatever they want.

My problem started recently with a changing of the guard at work. We got a couple new hotshots who want to show everyone up all the time and constantly steal credit for things I've done to the point they've even gotten themselves raises and me a reprimand. Sure, I could record them in the act but I honestly just don't have the drive to even care. I'm at a point I'd be fine if I never got another raise and at this point I was just waiting out my pension.

Recently I've started having heart palpitations. I think they are psycho-somatic because my pulse never changes... but it literally feels like I have a bird trapped in my ribcage. I get them when driving, I get them at home when I'm trying to relax, and I get them constantly when I have to work with these terrible people. I had a terrible panic attack at work recently and decided I needed a day off... then got home and decided I needed a week.

I have to go back, I can't keep this up forever... but I'm pretty much out of options. I've just had pills thrown at me every time I try to address this problem by numerous providers and now I won't even seek their opinions anymore. For the first time since I was a teenager it's just seeming like there is no light at the end of the tunnel and I can't remember feeling so confused and frustrated ever. My job is literally killing me, and my family will fall apart if I lose it. I couldn't live with myself if I had to go on disability but I feel like I won't live much longer if I keep working.

I've looked into other career options, but all my skills require me to work with others. I've tried attending uni 3 times as I test very well. However, I always stopped going when I had to speak in public or work in groups... so my options are quite limited in the job market. I just don't know what to do anymore. Losing this job would mean losing a killer pension... I would never make this kind of money again... and my wife will leave with our kids(she believes in her core only lazy people don't want to work and is a very social person so it did not go well when I told her what I was thinking.)
