MacBook Pro 15-inch 2017 Retina Screen

Two weeks back, out of no where, there are horizontal dark lines shown on the bottom of the retina screen. After a week, the same kind of dark lines appear on the upper screen around the utility bar. Three days ago, whenever I turn on the computer, there are heavy imagine retention effect, yet after a while it would return to normal. Today, the image retention persisted for almost 2 hours and the screen on both sides are constantly flashing/ flicking. The problem is getting worse day by day.

Please help.
