Cool Cool…
Now please sell them SDLs at discount on NSE/BSE.
A bunch of us are waiting to buy them at a steep discount. 
On a more serious note,
- Either forget you have them and hold them till maturity, earning interest on them every 6 months,
- or sell them off at a discount as described here
- assuming someone is even willing to buy them on the secondary markets (NSE/BSE).
- in this case even if you book a small loss (5-15%), atleast you have your capital back to trade.
