Think I have some kind of undiagnosed stutter?

Think I have some kind of undiagnosed stutter? I've had a lisp most of my life (I'm 20) but have managed to mostly overcome it. However I've realised that I still have some issues speaking which are kind of like a stutter. Mostly, if I'm speaking and am interrupted even slightly I lose my place and have no idea what i was saying, even when someone reminds me its like theres a brick wall surrounding what i wanted to say. Fairly often people have difficulty understanding me, even people that know me well act as if I've just spoken a foreign language. Does anyone relate to this? Any advice or good resources you guys coukd point me to? I may try join you guys on discord too sometime
