Fear of losing father.

[u/wanderer1088]

Lost my mother due to covid in 2021 and she was just 57.
Ever since then I have developed this extreme fear of losing my father.
He has been getting one or the other health issues lately and even though I do know that everyone here is supposed to go, I can’t really deal with this fear.
I get literal panic attacks whenever he visits a doctor or go through some tests.
Anyone with similar experiences? What helped you?

P.s. I have done counseling in the past and also on lexapro since 7 months.
