SOFI Bear Call Credit Spread :(

i studied options for three months before starting trading them November last year, and am obviously still learning, with a \~8k margin account, over 100 trades in that time, almost all selling/rolling CSPs for premium trying to avoid assignment, wheeling when assigned, have only done a few spreads, mostly it's been going well, have collected \~$1700 net premium, currently holding $1800 of assigned shares, but this one trade has gone badly against me, i sold a SOFI Bear Call Credit Spread 17/15 on 18 May expiring 5 June for $76 premium...SOFI closed at \~$18.20 today, it would cost me \~$200 to close it...interested in what experienced traders suggestions are about my risk, assignment chances, should i hold? close? roll? make it an iron condor or some such thing, create another SOFI spread to hedge?
