Hi! I come from a Linguistics background and I understand your struggle. However, I just got acceptances to my top programs!
If you are struggling with prerequisites, look at course equivalencies and see if anything can double-count or if you can apply and finish the prerequisite after you get accepted. You can also reach out to admissions officers and ask if the courses you're currently taking/have taken count as certain classes. For example, some programs require a Hearing Science course, but that is often covered in an Intro to Audiology course already.
I also recommend online programs with fewer or no prerequisites, such as Speech@NYU. I personally only took a few prerequisites (Intro to Audiology, Anat & Phys, Language Dev, Speech Science, Aural Rehab). Feel free to PM me if you have any questions!
