An I getting paranoid ?

I am having a medical appointment later this week
I’ve been having lots of weird symptoms likeheart palpitations, strong sadness that comes and go , feeling of impediment doom . Weight loss .amongst others… I’m kind of nervous about that appointment, Dutch doctors aren’t the best but what if there is nothing wrong with me ? What if that’s life now
?
Update .
Blood test is clean ish nothing wrong woth the heart/longs . Doctor suspect a burn out I’m surprise but not too surprise :/
