Just had an ADHD screening and I feel hopeless

I started suspecting I had ADHD a couple years ago, but as I’m sure many of you know, the process of getting a diagnosis goes directly against the symptoms I’m experiencing. I finally was able to schedule a screening, and ended up blanking mid-appointment. Suddenly I felt like I had no idea what I was talking about because I was worried about messing up.

Long story short, at the end of the appointment they essentially said, ‘you clearly have combined type ADHD, but because you also have depression we’re not gonna diagnose you’ and referred me to a psychiatrist to try treating me for depression. Again.

I am so tired. I need help and no one will listen. This is ruining my life. What do I even do from here? How do I get help like this?
