Is it normal i tear up non-stop when yawning?

When I yawn and get tired, usually others would shed a tear when yawning, but my eyes release a load of tears when I yawn. I try to dab and dry my eyes with a cloth, but I keep yawning and shedding a bunch of tears. Is this a medical problem? I want it to stop, as people confuse me for having depression as it is really common and see it as weird excuse.
