Took Screen off first and fear permanent damage

I destroyed my screen. Utterly ruined, So i decided that it would be a relatively easy replacement and descided to take it apart.

My screen was so damaged it had ridged on the side, and when i heated up the back so did i the the ridges of the screen, and pried to the screen apart when i intended to take off the back. I have no Ccamera to take to show to what stage im at with the phone, and I only work on analog edlectronics to a novice degree to my knowledge about digital is scant.

I suppose I can see what i can only presume to be the battery. With a yellow measuring like thing to the side….

am I &&^&@@?
