You've already had the best answers but I wanted to give my 2 cents as it differs a bit. My CH started as I hit 30, and soon after had two children. Having the added load of a young family to support when you're struggling to keep your job because of CH can push it over the edge.
I was close to suicide for a long time, when a chance but failed therapy helped me out the darkness. Back in the mid 2000s I had a sympathetic doctor but no official diagnosis. As a shot in the dark we agreed for me to try amitriptyline as it was used off-label for neuropathic pain. Although it didn't help much, and my doses were way below the usual for its supposed anti-depressant uses, I found that over a few months it gave me back the mental strength that CH drains from us so readily.
I stopped it when I was officially diagnosed, and moved onto Imitrex. Big mistake in my book, I am firmly of the belief that I received worse slap-backs because of that drug. Those 3 years were the worst of my life. I've been back on amitriptyline for 5 years and not touched sumitriptan since.
However, this does bring complications. You must thoroughly research any drug you are taking and how it might interact with the options available to treat CH. Of course, also discuss it with a medical professional. In my case, I taper off the amitriptyline for 2 weeks before busting (mushrooms / RC seeds) and that works for me. There could still be a risk involved with that, but frankly I am wiling to roll the dice on that one for the benefits I have felt (and by extension, my family).
Good luck with everything.
