The first truth is that you need to sell.
Have you point blank asked your Realtor "What do we need to do to get this home sold?"
I just helped a client with that same problem, maybe I can help you:
Since your home hit the market, how many homes, like yours, have sold? For how much? How long did they take to sell?
Also, your selling price should be based on market factors only. My client had his property listed to too high, way too long, and because of the bad advice really took a loss.
In your case it may not be impossible to sell for the price you want. The market picks the price. You definitely need a Realtor that is being honest with you about your home's value. OTOH, I would be careful not to blame the Realtor if you are the one not reducing the price.
HOmes that sell in the first 30 days sell closest to asking price. So the longer they sit, the more value they lose. Overpricing a home in most cases will result in a lower sales price in most markets.
