My tooth (no 19) has a crown. It is sensitive and hurts when I press it on the corner with my fingers. Am I losing it? (Photo)

Tooth 19 had a large filling for 10 years and put crown on it 6 months ago by dentist recommendation.End of Feb, tooth 14 was extracted.End of May,I woke up 3 nights tapping on tooth 19 with my tooth 15 hardly(not sure how that happened).After that day it started to hurt when I press it.Saw two dentists and told its because of malocclusion that there is no tooth on top of it and need my implant ASAP. I am very miserable and sad. It randomly hurts (sudden burn) and if i press it hardly it hurts
