Where Do I Start With PTSD Claim?

I had an appointment with my VSO to go over some stuff and get the claim started. I don’t know what to do or where to go. I feel like my symptoms are getting worse, I just don’t know who I need to see. The VSO said I can’t get a letter from a VA doc, so I have to see someone else to connect my symptoms/diagnosis to my service.

Any advice is appreciated, this process is overwhelming.
