That sounds really frustrating. Even if the doctor believed he was unable to help you and that a psychiatrist would be a good next step, it sounds like he conveyed that in a very insensitive way. I developed insomnia several years ago when I had a very stressful life event. With the help of a sleep specialist (psychologist that does cognitive behavioral therapy for insomnia (CBT-I) and my GP, I have improved. I also take some sleep meds as needed, prescribed by my GP. I will say that I too had vibrating sensations internally while going through the worst of that life event, several years ago. The psychiatrist said it was due to my anxiety at that time. As I worked through the situation, and with anti-depressant/anxiety meds, it eventually went away. So, perhaps a psychiatrist is a good next step for you. If you have friends or other medical practitioners you respect, I would try to get a recommendation from them. I dislike just choosing a doctor, knowing nothing about them. However, sometimes it's the only option. I know it's a pain to look for practitioners but it's important to find one who takes you seriously and will work with you to improve. Best of luck - don't give up.
