Yes, I would keep your BTC.  

From what I've gathered online, obtaining forked coins is rather difficult and has a lot of risk in that you can lose your BTC by claiming the forked coins incorrectly.  

One option you could do is invest the coins into an interesting project that has more upside potential which would have the added benefit of taking your mind off of the rollercoaster ride in crypto land recently.  

Another option is you can use your BTC as collateral if you are needing the funds. Salt Lending is one option.  I haven't used them so can't recommend them to you but it's worth researching all of your options before making a decision.  

 Not sure where you are, but the taxes on selling BTC is crazy here in the US and this approach avoid taxes. Of couse, you would have to pay back the loan so that's something to consider.  

I think the best thing is to stop watching it and find something else to focus your attention on for the time being.  My guess is you'll be glad you didn't sell 6 months from now.
