I have actually been in your situation very recently.  I took my first "real job" last year and was so excited to start at my "dream job."  I actually made it through the first couple of days doing fine, then the anxiety attacks set in.  I know what it is like to be scared that you are going to die during an attack, those that haven't experienced it have no idea.  I found myself lying on the cold bathroom tile with a wet towel just to keep myself from passing out.  I quickly quit my job to escape what I perceived to be the cause of my attacks. 

As awful as that situation is you have to realize that it is your job to take control.  You need to talk to a doctor about prescription meds that may help with a possible chemical imbalance.  Additionally, (as much as you may not want to) you need to seek a therapist to speak with.  This can help you sort out the real cause of your attacks.

Once I took these steps, I was able to seek out a new position.  I will not lie, I cried for days before I started the job and even the first days I worked the job.  Everything made me worry that an anxiety attack was around the corner.  I am proud to say that I worked through these fears and have not suffered another anxiety atack.  You just need to learn to face your fear, figure out what thought it is that trigers these attacks, and learn to question that thought.  Are you being realistic?  Will something awful happen just because you go to work? Are you allowing the attacks to beat you?  You have worked to hard in life to give everything up now, you deserve it and so does your spouse.
