I have a large symptomatic gallstone, does that mean my gallbladder is not healthy?

You have a stone: which can become symptomatic, Discuss with doctor to see if scan showed any signs of gall bladder inflammation.

Yes: Gallstones are a sign of a diseased gallbladder, and when causing symptoms such as abdominal pain, nausea and/or vomiting, the most common treatment is surgical removal of the entire gallbladder. Usually this is done laparoscopically (small cuts using a camera), as an outpatient or overnight stay by a general surgeon. Hope this helps!

Correct!: You have symptoms and a large gallstone. You should have your gallbladder taken out. Your gallbladder is NOT healthy

Most likely: If you are symptomatic and surgeon thinks from GB then it likely needs to come out. He/she may do a HIDA scan to confirm that it is unhealthy. Asymptomatic cholelithiasis with normal labs can wait to be removed as not urgent. The goal is to fix the problem causing you pain and sometimes a gallstone isn't the thing causing the pain. Talk with your physician/surgeon about it.
