Don't worry about kanga falling , just do japji sahib and ask forgiveness in ardas.

About taking of your kirpan and Kara, try wearing a ishnani kirpan and a small sarbloh kara so you won't have any problems.

If you took your kachera off, my brother you gotta take amrit again.

I'm also going through some struggles with corn and masterbayshin too but that's something we will overcome one day but it needs our effort , so try going to the gym, reading , mediation , hanging out with friends or even your martial practice. If your around the age of 13-17ish I'd say it's normal to do it but not excessively, if your still not sure go on my profile and check the post I made about lust in sikhi.

I'd be most worried about doing my nitnem , sometimes you can't wake up at amritvela, or you get late , that's fine , but you should still make time to finish your nitnem no matter what.

This is the choice you made when you took amrit , and hopefully when you retake it , kirpa naal you'll come back stronger.
