Sorry Rachelle, I don't have any advice. I'm in a similar situation, aged 38 with virtually nothing in place for my retirement. I have no idea how much I would be expected to put away each month to provide a comfortable retirement, but I'm pretty sure it would be way more than I could afford right now.
A lot of people seem to be investing in property as a retirement fund these days, which I know has faced a lot of criticism lately, but it is something I have thought about a few times. A small house purchased on a 20 year mortgage. Rent from tenants that would cover the mortgage repayments, and after 20 years when the mortgage is paid off the choice of a monthly income from rent or a lump sum from the sale of the property. I know it wouldn't be that simple and would be a lot of hard work and planning, but worth the thought, I think.
