Stay in a risky-ish CCIF , vs liquidate and pay down on mortgage

I own 20,000 shares CCIF, a closed-end fund with a crazy dividend of 15% +/-. It pays (all last year, and thru May of 2025) a MONTHLY dividend of 0.10 (ten cents) per share - so $2000/mo in dividends (this is in a taxable account). Share price has been hit with the volatility of the past few months. We can presume that a recession or worse will mess with default rates. Even before the recent drawdown, the fund was paying a small portion of the dividend as 'return of capital' - which is (I think) dilutive and just paying you with your own money.

I also have a new mortgage on the home I recently purchased - $285K at 6.5% via a HELOC. Payment is $1543/mo. I am torn between just staying as-is, my CCIF dividend is covering my mortgage payment. OR - sensing that there is a risk profile to hanging onto CCIF (potential dividend cut, and/or further share price erosion) - I could sell the CCIF shares (trading now at $7, my cost is $7.45), and pay down the mortgage by about $140K, cutting my payment in half and avoiding the risk in owning a single CEF in this volatile market.

Thoughts?
