Extra Curricular Dilemma - Please help

I am currently a senior in high school and I am wondering whether or not I should drop one of my extracurriculars that I am supposed to start in a couple of weeks
End of junior year I volunteered with a program that teaches disadvantaged low income kids reading and comprehension skills (once a week for an hour)
However, now that it is senior year I am now going to be

  • volunteering at hospital emergency department for at least 4 hours a week
    -volunteering with program that offers therapeutic horse riding lessons to mentally disabled children
    -starting my own NAMI (nationa alliance on mental illness club) on my school campus which i will be president of which will meet 2x a month along with all of the activities that will happen within the club.
    Should I drop the reading volunteering thing, as I feel I will be spreading myself out way too thin with all of these extracurriculars? The only thing I’m worried about is that college admissions will see that I suddenly stopped doing one of my volunteer activities and that I’m not consistent. Will this look bad even though it’s being swapped for something that deals closer with mental illness and probably is more related to my major? (psych. is the major I am applying for). Please help

If you haven’t started an activity (“I am supposed to start in a couple of weeks”) why would an AO think that you "suddenly stopped doing one of my volunteer activities "? Why would you list it as an activity if you never started?

If an additional hour a week makes you think you’re spreading yourself too thin, then don’t do it.

no i did it part of my junior year but am thinking of not continuing doing it senior year

It’s fine - and you don’t even have to list it as an activity from junior year if you are worried about someone noting it’s absence from your senior year activity list.
