I need help in something that I try to figure out a month!

I want to make in unity that when I come into a collider of object a text will apear, lets call the text “FirstText” and when I press on F two more texts will apear, lets call them “ToContinue” and “SenOne” and the “FirstText” will disapear and when I press on Space “SenOne” will disapear and text that called SenTwo will apear and if I press on Space again a text called “SenThree” will apear and “SenTwo” will disapear and if I press on Space again “SenThree” and “ToContinue” will disapear. I tried so many scripts and thing to do and I dont found how to do it so if somebody can help me this will be realy nice, thanks for reading;)
