Help, Accidental subscription of Adobe Stock

I am a student and am subscribed to the EDU plan for Adobe Creative Cloud. It's my second year using the service so I'm paying the second-year rate which is slightly more expensive. However it also seems that for the past 3 months I have been subscribed to Adobe Stock by mistake, and have been paying every month until a billing error occurred this month. I don't even use the service.

I cannot afford to continue paying for the whole rest of the year, as I am already struggling with finances as a college student abroad without scholarship. I understand that it may have been a mistake in my part, but as a loyal Adobe customer, is there something that can be done?
