I am not a regular trader but once in a while I buy some stocks that I think will grow and just leave it like that for the long term. I recently found that one of my stock Birla Cotsyn which i brought as IPO has been suspended from trading. It lost almost all its value and it is currently valued at .13 . I definitely did not do proper research when I got it and fell for the birla name 
What do I do with this stock? it seems it is worthless at the moment with no good longterm outlook. Since it is suspended from trading I can’t sell it I guess. Am I right with my assumptions? what are my options should i just leave it as it is and forget about it?
