Do I see a little hope? Oh no, never mind

I was diagnosed with migraines at 16, I am now 37. I managed most of my life with abortive meds, but as I got older there was nothing to "abort" the pain was constant. I worked a very physically demanding job, but because I worked three 12 hour shifts it was easy to get people to switch shifts when I was feeling awful. About two and a half years ago I stopped working and applied for disability. I finally see a judge May 8th. I'm home bound, I don't drive because the dizziness and falling is so bad and I can't shower unless someone else is home. I have Vestibular Migraines, with the migraines themselves being the ice pic through my left eye variety. I really would sometime rather blow my brains out than deal with this. I have done a five day inpatient stay for DHE infusions, Botox, Spine injections, PT, Accupuncture, massage and Chiropractic adjustments (did get some relief from the adjustments, but my insurance will no longer pay for it). I also have abortive DHE and Sumatriptan injections collecting cobwebs at home. You name the preventative and I've tried it (but give it a whirl, maybe my docs have missed something). I was put on Propranolol (not smart when you are already dizzy and fall all the time and are hypotensive). I am also bipolar, suffering more with depression than mania, the Propranolol made me suicidal (that is a very powerful drug so PLEASE be careful with it). I have had no success. My neurologist is the top doc in my state and finally shrugged my off and told me she really didn't know what else to do, so she gave me paperwork for medicinal marijuana ( haven't been approved by the state, and really hesitant, but some say it's a miracle and I need one). Went to see an ENT who specializes in migraines and balance disorders, perfect! He gave me an Sphenopalatine nerve block right in the office (I think I've seen people call them SPG's), within 90 seconds I had no pain what so ever! His hope was to treat the migraines first, then deal with the vestibular nerve. He then set me up with 3 more with his NP. I went 2 days pain free. Like I said, I starting having migraines at 16 and I am 37, I have never been pain free for 2 days! Fast forward, saw the NP and his technique was totally different, which I mentioned, and he told me that technique didn't matter the result was the same...WRONG! I decided to go back to him for my next appt (2days later) and address my concerns, I even brought the paperwork from the initial visit with the Doctor and he got super defensive. I assured I wasn't trying to insult him, I just wanted to come up with a way to ease my pain and he told me, if I didn't like the way he did it, go back to the Doctor. BTW, he did the block, no relief and I cancelled my third appt. I called the office and they told me my doctor is booked until May (it's literally a 10 minute procedure at best, no prep, no sedation). They said they would work on trying to squeeze me in. At this point I just want to see if the Doctor knows what he's doing and the other guy didn't or if the initial relief I got was a fluke. I am so desperate for relief. I'm back to being in agony, I don't know what Doctor I should ask for help from, as in pain meds, or if I should even bother. And like many others the ER is off the table. Any advice, suggestions, others who just want to get their frustrations off their chests? HELP
