How can I not be scared to go for a mental health diagnosis?

Anonymous
Sorry this is quite a long post but thank you if you read it all lol.

I have been having counselling throughout this year, and I have spoken to 3 healthcare professionals. They have all said I could be suffering from Obsessive Compulsive Disorder, and 2 of them suggested I see a GP to be checked or diagnosed. I put it off at first because I was scared. But when the 3rd professional mentioned the GP just a few days ago, I thought it is something I should do and not put off anymore. So I've booked an appointment with a GP, but I'm still scared.

Firstly, I'm scared that the GP will find nothing wrong. It's not that I want something to be wrong, but I have experienced many symptoms since I was 9 that don't sound healthy, especially for someone as young as I was when it all started. Some symptoms sound particularly scary, so I worry that if nothing is found then maybe this is just who I am rather than something in me that can be treated. I would be confused and worried about how to overcome it.

Secondly, I'm scared because I will have to hide it from my family if I do get diagnosed. When I told my mum and sister this summer, they were concerned thinking that a demon/evil spirit caused the symptoms. They wanted to take me to church to speak to Godly people about it. They also believe a GP could lock me up in an institution and that my chances of having a job can be affected. Because of this, my mum has asked me not to tell anyone (apart from Godly people). I'm 21 and old enough to do this but I feel kinda bad going behind their backs.

Thirdly, it would be difficult to explain it to e. g future boyfriends, friends etc, especially if I'm in a situation where I'm caught doing something. The symptoms are based on some sensitive subjects, so I wouldn't want to be looked at funny.

I don't want to overthink it or anything, but I'm scared. Is there any way to be less scared about it?

Hi everyone, thank you for your support and for answering my question. I saw the GP today and they identified OCD with an element of depression. I've been prescribed with some medication, so I hope to start getting better! xx
