Hello, For Years Now I've Been Suffering In My Own

Hello,

For years now I've been suffering in my own head forgetting words and feeling like I can't string sentences together properly and cannot keep people's attention. I worry and think about what I want to say next and don't listen or take things in properly. I'm thinking about starting a family in the next year or two and want to sort this out so I can explain things clearly for them and teach them like I know I can. Other people have said they don't notice it, but I hate the feeling of anxiety that constantly comes with it. My memory has gotten terrible too.
I wondered if you could point me in the direction of what this may be and what I can do to help it go away. Thank you.
