I really hope someone replies.
I’ve been thinking a lot lately about my mental health and how has life been for me and now I’m concerned and confused.

I noticed some things about me, I didn’t really know if it was depression or something else, I just had so many things happening and after a kind of long time I found out about BPD. At first I just wanted to learn more about it to be more informed and be able to understand the people who have BPD because mental health is a stigmatized topic, but then I started to read more about it and noticed I could relate to almost every symptom which I have been struggling with constantly since a long time ago. I must say I am and was not trying to auto diagnose, I just wanted to know if anyone else could relate to my situation or I was just weird or wrong. 
I just felt sort of relieved after so long after finding out about this, but don’t want to jump to conclusions. I want to get a proper diagnosis, because I think I need help either if I have it or not. 

The problem is that I’ve always dealt with my own stuff and kept it inside so I’ve never actually been to a therapist or psychologist. I don’t know what to do really, how to approach the issue, I feel that if I ask for a diagnosis they would think I’m a hypochondriac, like “Oh so because she read it on the internet, now she thinks she has it” or “No, you’re just being over dramatic”. I don’t know if I have to start telling them what I feel instead of what I think is the problem or something else and asking them directly. I also don’t know how to ask my parents, I never talk to them about this kind of things.

So if you have any advice please leave it in the comments, I will be very grateful.
