Can speech therapy help an adult or is it too late?

I am a grown adult and have through stuttering phases my entire life. It’s worse at times depending on what is going on in life or around me in general. It is getting to the point where it is interfering with my daily job, etc. and honestly, it’s embarrassing to me. I’ve came to think that maybe this could be related to something else, health related issue, etc. but at my last check up everything checked out perfect. I need some advice on what to do because I have found myself in some really uncomfortable situations because of my stuttering. Thank you to whomever in advance.
