You sound like me and the many others in my aphasia group and that’s what you really need to be looking into.
I’m lucky with how I handle it purely because of my very nature. I’m a quiet person in real life, a bit of an introvert and always the type of person who thinks what I’m going to say before speaking, so inevitably I miss my ques in conversation now and again 
I just don’t care 
And like you, no one notices.
So as well as getting a referral for speech and memory therapy, also get in touch with any local aphasia group going on near you. They can all relate to you and will be able to point you in the right direction locally.
Hope you don’t mind, I pulled this from your post last august
Did you ever get any help for this, have you tried the Dyslexia Association, they have a helpline you could also call for advice.
And lastly, as I’ve been banging on about nutrients elsewhere on here, so I may as well give it to you too
Not all symptoms have to be stroke related, and seeing as @Mrs5K has already broached the subject, it would do you no harm to start taking a menopause supplement anyway.
