First off, I hope this post doesn’t violate the rules of the sub, apologies if it does.
I’ve been lurking on this sub for a few days, absolutely laughing my ass off because the things you guys say resonate with me so much.
My mental health has been pretty bad since starting a new job 6 weeks ago, and my previous experience of deteriorated mental health has convinced me that this time is not like the others—I am very slowly and painfully connecting some dots that point to BPD being a possible diagnosis.
But at the same time, I keep questioning myself—maybe I am blowing my symptoms and feelings out of proportion? 
I’m not sure how best to suggest to my doctor that this is something we should look into—I’m afraid I might get laughed at and told I’m overthinking. 
If any of you could give me advice on 1) whether I should take myself seriously and 2) how best to ask for an assessment for BPD with no previous medical concerns relating to it, please please offer it.
Thank you.
