Cover art for Doubt lyrics by Twenty One Pilots

'Scared of my own image Scared of my own immaturity Scared of my own ceiling Scared I'll die of uncertainty Fear might be the death of me Fear leads to anxiety Don’t know what’s inside of me'

my thoughts is that these lines are the thoughts someone has at night. scared of my image is being afraid of what you might do to mess it up...scared of my own celling refers to where a rope hangs from to...end your life... . and all of this will lead to anxiety and more anxiety. when he doesn't know whats inside of his is when he doesn't know what'll he'll do or what is happening to him.

"don't forget about me"

this line means that he is scared he'll loose something important to him and that he'll be left all alone and the person he is referring to will just leave him for someone else.

'I'm not sure if I can See this ever stopping Shaking hands with the dark parts of my thoughts No, you are all that I've got, no'

this part of the song means that he doesn't know that what he feels will ever stop along with the shaky hands and dark part of his thoughts. he just feels like there is no end to this hell. lastly, he feels like he's loosing the only person he really knows and cares for

My Interpretation

@devonbarks I should reiterate a bit. The verse "shaking hands with the dark part of my thoughts" I believe it means he's afraid to give in to his inner desires that tend to be immature and possibly sinful.
