I heard a story you might be interested in; might help explain some of the "attitude" out there with the people you're interviewing with... etc.
BILaw manages a pretty big company. He's been trying to replace some temp workers with a f/t person, because they're in the process of making a deal to do some more work for another company - and they need a stable crew of workers. Decent pay, good benefits, training, advancement, etc. They have offered jobs to people, who hemmed & hawed, had to think about it... or wanted to dictate how many hours and which days they would work. Most were trying to just supplement their unemployment benefits - and wouldn't jeopardize that with full time work.
Some were older people who were trying to completely change fields - requiring training, apprenticeship, etc - before they would even get an income. They were turning down a firm job offer for long-term investment in a "maybe".
Really makes a person like me go "HUH?" and probably irritates someone like you more than you need to be irritated right now! But, I think you could use that bit of anecdote to your advantage; it's an important piece of info about what's going on "out there"... because these HR mgrs, interviewers, and owners who are hiring don't want to waste any more time trying to sift thru all the apps, calls, interviews only to make an offer to someone and have it rejected.
I don't know how much you want to reveal about yourself to potential employers, but there is one thing I think you could say very plainly, unequivacably without appearing desperate or without sacrificing any dignity: I want to work again. I am reliable, learn quickly, and will be an asset to your business. A lot. And mean it. And, though I normally wouldn't recommend this to anyone, anytime - times have changed and sometimes that calls for a different strategy:
Normally, there's this negotiation & getting to know you phase when interviewing. And the interviewee is usually trying to make a good impression while also evaluating the place of business and the people in it. (I suggest people do this because of some fraudulent experiences I've had during interviews; it has to be subtle.) Sort of aloof... you have to talk about yourself and be friendly... but everyone gets a little self-conscious or protective of themselves in these conversations... and everyone has things they'd rather not have their potential employer know about them during this phase. So one's emotions are generally pushed as far away from the interaction as possible...
... well, for you in your circumstances, I think a little emotion might be something that will help you get a foot in the door. I don't think it hurts to express (professionally) that you prefer to be working; busy; doing something and that unemployment scares you. I also don't think it hurts (these days) to also look at and express ways your past experience could be stretched or applied to something that was related to, but not the same that you did before. One more thing, and for you personally, this just might be the thing that lands you your next job:
You write very well*. This is not something that will probably show up on your resume or avg. application form. However, it IS a skill that is increasingly valuable out there in the real world and an advantage to you; an edge over the competition. Trust me, the level of writing skills these days is absolutely appalling. The way to make this known to an employer is to write a cover letter - and not the std "I'm interested in your open position"... business letter. The cover letter is where you can be creative, maybe you have an intuition about the employer's working environment and your writing can be the way that you prove you'll fit in... and it's the best way for some people (me included) to present a personal, "here's who I am and what I can do for you" offer. Even if it's not a required part of an application, send it anyway. And make sure you customize the letter to each employer - you are introducing you with it - and they have something you want; your attention to those kinds of details will make an impression.
I've seen a lot of letters where people created a form letter - and then forgot a couple places where they did a search/replace. Not good.
Then, I guess it matters what kinds of jobs you're applying for. Your last couple of posts lead me to believe that you have a real interest in healthy food (and the preparation of it). There might not be many jobs out there - advertised - in smaller cafes or health food stores. The best way to find those, is to be a regular and get to know the people already working there.
PS* - I forgot to say, that there a lot of jobs out there - not writing jobs, per se - where being able to write well (and proofread) is a needed skill. It may not even be listed in the "requirements" for the job, but you can figure out which ones that applies to.
