In some ways, i go through something similar but mine is on a smaller-scale and it's mostly linked with OCD.
Anyway, i'm really proud of you for having the courage to book that doctor's appointment - this is the first step! The second is letting them know everything that's bothering you, in order for them to help you. Yes, it's really awkward and embarrassing but trust me the doctor will not laugh at you or look down upon you - the doctor sees cases like this every single day, and that is his/her job to provide you with medical care and to listen to your problems especially if they are affecting your health.

So try your best to tell them everything. Just know that after this, hopefully you will recieve the correct treatment and you will feel so much better for it and relieved knowing that all it takes is to tell somebody!

As for blood tests, they are usually taken if you show any physical symptoms for certain things, so i wouldn't worry too much.
