Retirement or lack thereof

Once again I don't know where to put this topic.I put it here because I am loosing sleep over this and my mental health may suffer if this topic doesn't get resolved and sleep continues to escape me.
I went to a "financial planner" at our credit union this week.I have about 10-12 years to retirement. I'm scared!!!All toll, at age 64, I'll have a whopping $1,700.00 to live off of a month.Much of that will have to go to medical.(My school system doesn't have a medical plan for retirees.)I have to take $300.00 more out of each paycheck a month now to have $150.00 more a month then.
Good reasons why I wasn't able to save more sooner,but is anyone else concerned about their retirement years?

I believe there are going to be lots of baby boomers who are unhappy because retirement is going to be much later in life due to the lifestyles we have chosen.

I WAS retired during my hubby's illness and for almost 2 years after his death. and our nest egg is gone. I am alone, working to keep the wolves from the door. It is a struggle, ecpecially since I have no real skills except this darned CDL B license and my "mouth of the south". Everything I did before the forced retirement is no longer usuable and I am working for a school bus company that pays by the hour. I am just doing my best to keep my head above water day by day. What happens in the future will have to happen--I can't put anything aside at all now. I don't have any regrets because the money went to make his life better for the last 5 years of it, and if my dogs and I have to live in the truck, then we will. I am grateful for the time we had together, 24/7 from his diagnosis to his death, and I wouldn't trade that for a mansion or all the money on earth. But, that said, I do think about it, too. I am 54 (55 in August) and I see what I am doing for my elderly aunts and uncles that have no children, as I don't. It is scary to think that someday everyone will be gone before me and I will have no children either. I guess I just have to give it to God and see what hisplans for me are.
