Check for stiff links in the chain, perhaps it needs some lube?
If that is not the cause then without seeing pics or knowing more about it, sounds like your chain is excessively worn and you will need to replace it along with the cassette/freewheel. Have you tried measuring the chain for wear?

Which are you calling 6 and 7? The larger of the cassette cogs or the smaller?
Technically 6 and 7 will be the smaller, further away from the wheel (these give you higher gearing).
Some people number them the other way around, so that the larger inner cassette cogs are 6, 7 (8 etc). If that is how you are numbering them, then you shouldn't be selecting "above 6 on the big cog and 7 on the mid cog" - because doing so is inefficient, wears chain, rings and cassette and may well cause the chain to slip massivel!
Sounds to me like worn chain and cassette, its not so much how long the chain has been on the bike, but how much mileage you have done and to what standard has it been maintained. I used to wear a chain out on average every month and half, aprox 1200miles, but since I changed my lube I now get nearly 3 months and roughly 2400 miles.
But as a rule, I have always found in the past, that if you just run a bike on the same chain, chain rings and cassette, I do not have a problem with skipping. My Raleigh road bike was over 20 years old, worked perfectly till I scrapped it, the chain was well worn out, but it never skipped. My 10 year old MTB, has never had anything changed, yet works perfectly, I did change the chain and it skipped like hell, so I put the old one back on, and as it is only for commuting to work in the snow and ice, I'll just run it to destruction.
But one of my newer road bikes, only lasted about 6 months before I had to change every thing as all the transmission had been worn out and skipped like crazy. Maybe they don't make them like they used to do.

Wait sounds like your lock ring has come loose on the cassette the two smallest cogs are loose and are tightened in place by the cassette lock ring. Needs a specific tool but dead easy to tighten.

If some of the cogs within a cassette can spin freely in both directions, then most likely the splines of the freehub and therefore the freehub is goosed. How much it will cost to fix/replace depends on the wheel - you might be able to replace just the freehub, or you might have to replace the hub, or you might find it more economical to replace the whole wheel.
Separately this shows you how to check to see whether your cassette/chainset/chain is worn.

If the small cogs are spinning on the hub your lock nut is loose. Buy a suitable adaptor to fit your cassette, remove the wheel and tighten it. If it won't tighten then the freehub will need replacing. This is no real issue and you could do it yourself, but the LBS will/should do it cheaply. And three years old is plenty if you ride several thousand miles/year.
