Hang in there Red - something WILL come up. It might not be what you want and probably won't be what you expect, but you will find work. The loved ones thing is very hard for all concerned and hurtful for you. It grinds you down. Like most middle-aged men, I've been unemployed before and both of my sons have struggled in the past. In my experience, the digs and comments are born of worry and fear rather than any lack of love. "You're not trying" is the easiest arrow to shoot and one of the most hurtful. Luckily, it's also one of the easiest to defend if you are doing your best. Tell them. Show them. Calmly and in detail. Take anything you can get that will bring in more than you're getting now, will keep you occupied while you search, and may lead to the opportunities you really want. View this as a test and remember that most issues are resolved through flexibility and ingenuity rather than just blind effort.
I don't know you so can't comment in detail, but I hope this encourages you. 14 years ago, I was running a number of successful UK financial printing firms for a US parent. I was hired when they moved to this country and built up every firm they bought through massive drive and effort. I put everything into that company - including financial investment - and when the banks suddenly foreclosed on the parent I lost everything. I had to lay off all of the staff and go home to tell my wife that we had lost our house, cars - the lot. We were left in debt and destitute. There was chaos. After a couple of makeweight jobs and more heartache than I thought it possible to bear, I saw an opportunity to move into a totally different industry, took it, and worked my way up from the bottom. Again. The experience I gained in that field opened another avenue which looked really promising, so I moved sideways and have never looked back. Hard work isn't enough. It has to be tied to courage and flexibility if you are to succeed.
Apologies for the long post. I'm not preaching; I just hope this helps. Good luck!
