Parents inducing bad anxiety

I have been experiencing higher than average anxiety lately.. I’ve had frequent panic attacks, it’s affecting my work and my relationship with my husband. I know my anxiety is related directly to being an only child to parents who are aging too young. I don’t know how to remedy this… I notice my anxiety skyrockets when I’m around them or when I talked to them … I love them dearly and I want to do everything I can to help them but how do I preserve my sanity? Of course I’ve not told them anything about my anxiety and I do without complaining .. but I feel im going crazy.
