How do you explain to someone your mental disorder?

I have SA and GA both social and general anxiety. Basically I’m OCD without the ritualistic behavior (a poor and un educated comparison but it’s how i generally describe it). I have trouble conveying to others especially my boyfriend what it’s like and how it shapes my life. Is there a way I can sum it up and explain it or should I just deal with the fact that we have a misunderstanding when it comes to my mindset
