Obito's unhealthy love can be better described as "Uchiha" love. As Tobirama said, the Uchiha is a clan possessed by evil because of the way people within the clan treasure love.
Obito's love for Rin is very strong, similar to Sasuke's love for his brother and parents, if not more. When a Uchiha loses such love, the stressful condition brought out from losing that precious person causes the brain to release a special form of chakra that affects the optic nerves while transforming the eyes into the Sharingan, leading us to assume the Sharingan is a "symptom" that can measure how strong are those person's feelings.
Rin's death caused Obito's Sharingan to transform from two tomoes into a fully evolved Mangekyo Sharingan instantaneously.

If you look from the perspective that this love is the reason behind many of the disastrous events that happened throughout the serie, it's not wrong to say such feeling is unhealthy.
That's the part where makes me rage, what makes the uchiha so special then?
Nagato went though the same, the difference is that they got more power and that's all.
they dont suffer more or less than "normal" people.
Kakashi went though the same so just because he wasnt an Uchiha he didnt wanted to destroy the world?
That was the crappiest explanation and a fail attempt to make them look like victims from Kishi.
Madara caused so many disasters in the world, Obito was behind the whole Mist Ninja village which make them to be known as the village of the bloody mist.
Love is not the cause of disasters it's just that they act like immature kids like Madara asking Hashirama to kill himself, there were people like Itachi, Shisui and others who surpassed that.
Look at Madara, he almost destroyed his own clan just because his brother died because it was his fault for wanting to continue waging war when he knew he could not win.
