Hello Waterknob: What causes you to think your post might be viewed as ridiculous? This is an important & difficult situation. Back when I was still a real person, I was a vocational rehabilitation counselor. So I am sensitive to the issues & concerns surrounding your predicament.

I think one of the first things I would want to try to figure out is what aspects of your present job cause you to be unhappy & stressed? There's no point in jumping from your present job (where if nothing else you at least have familiarity) into another similar job where you're brand new & under the gun, as they say, to perform or possibly be let go before your probationary period ends. Since your present job is causing you to be unhappy, it may be important to try to find a different type of job or at least one in a less stressful environment.

I certainly don't see any reason not to set up the interview you mentioned. The reality is it may be unlikely you're going to be offered the first job you apply for. Effective job seeking is a skill in-&-of itself. It's something job seekers have to practice. So I always used to encourage clients to go out & interview for as many jobs as possible, just for the practice as well as to learn what types of questions employers are likely to ask. The job seeker can then hone his / her answers to these questions. This process also gives the job seeker an opportunity to see what kinds of jobs are out there & what employers are looking for. If it should happen that the person gets an offer for a job they don't want, it can always be turned it down.

The health insurance question is also an important one. I take it you have health insurance through your present employer. I would be reluctant nowadays to recommend anyone go from an employment situation where health insurance is offered to one where it is not. The whole health insurance environment is in a state of flux at present what with the passage of "Obamacare" & the Republican Party's opposition to it. Health insurance is important. I'm sure I don't have to convince you of that. I would want to think seriously before I left a job with health insurance to go to one without. (Of course I'm assuming you live in the U.S. as I write this. If not, perhaps your health insurance situation is less significant.)

Of course, the other side of the coin here is your present job is making you unhappy & contributing to your stress level. And that's not a good thing either. So I would certainly agree an effort to find new employment is in order. Have you checked to see if there are any type of vocational services which might be available to you; perhaps based on your present health situation? This might be one avenue to explore. Is there any possibility you could transfer to another position within the same company you're employed by now?

Well, these are my thoughts just off the top of my head, so to speak. Best of luck with this.
