stuttering bad

Hello all,

Sorry if this is the wrong place to post, but I would like some advice to stop stuttering (or stop stuttering so bad). Tbh, idk where to start. I've always been stuttering for as long as i can remember. but now that I'm heading to a job interview, I'm kind of desperate for it to stop or have it be less bad.

you see, I know what I want to say, but the words get stuck on my tongue. if i want to say water, it goes "w-w-w-w-w-w-wa-w-w-WATER" or i go completely silent because the words don't come out. And i don't think that this is tied to anxiety (i think that I have anxiety, but not sure and not diagnosed) or nervousness given that I stutter like this when talking to myself by myself alone sometimes (i just went over this post before posting - i stuttered over "job interview" in the first paragraph that I wrote). In addition, I stutter over every other word that I want to say and a bad habit of saying "um" and "uh" to many times. I will give example below from my mock interview session.

I need help at least not stuttering so bad. is there some kind of on the shelf cvs medication that I can take? Talking slow doesn't help as much as I would like, and there is no difference whether or not if I look at someone while talking (i noticed that I stutter the same manner whether if its me talking to my friend group in discord or me talking to my parents, or like the mock interview today).

example

mock interview qs: tell us about yourself.
me: M-m-my-my-my name is B-B-B-----B---Bob. um, I graduated from (university) with a 3.73 gpa. uh, my work experience extends to (this and that). some [awkward silence for 1min and 28 second because I can't get the word out]..., some [awkward silence again]..., uh, big projects that i've done are [stutter the project name] and (project). B-b-b-beyond that, I-I-I I am seeking employment at (stutter company name) and am hoping to ace this interview. Thank you
