KWR is right. No crisis in life does not come to pass. Everything gets better if you make the effort to, or very often simply in the passage of time. I am a very emotional person and I feel everything very deeply and strongly, but still even the worst of times pass.
I do think that maybe making aliyah would allow you to clear your head and get a fresh start. Yeah you can't own guns there but you will be able to carry on the fight for our movement where it matters. A sober-minded, mature guy like yourself will be able to talk a lot of sense into a lot of left-wing Jews and help Hayamin grow bigtime. But whatever you choose to do, we'll support you. There is never such a thing as no way out. You are valuable to us, the movement, and G-d. Taking your life solves absolutely nothing and makes the Arab scum cheer.
