Again anxiety with covid

Hi, What I feel is this sudden trembling in my leg and hands ... I dont know when did it start getting bad... But Whenever I see any unusual behaviour in my parents or my health I just start getting weird thoughts... I have stopped watching news or anything related to covid since this is hitting me that bad but that doesnt slso work ..I always have this fear inside that what if they will not say snything because they think they will manage it? What if I get effected and it makes them suffer? Writing this now still giving me weird feeling... Its been looong since I couldnt stop thinking like this... Now I am exhausted.I sm genuinely exhausted and just want to free myself from this desperately.... Sometimes I think I'll always like this from now on.... Any help or advice will be really appreciated..
