How to find all the people blocking you on instagram?

[Esta]

OK, so I wanna find ALL the people that are blocking me on instagram. I know when someone is blocking me the follow button acts weird and it says on their profile that they have no pics. I know this, but is there an app or some website or something possibly on statigram or anything that will show me a list of everyone? So far I know 5 people blocking me. Idk why, they're all from my school, they just have issues, just ignore that. I just need to see if there's any more people blocking. Oh and does anyone know the limit of blockers you can have? I really don't want to lose my instagram Thanks for your help if you can, I'd really appreciate it.
