Thank you for sharing your situation, Alyce. I am sorry to hear that you have suffered bad experiences with your past guilds.
I remember walking beneath the canopies of Kalimdor since the leaves themselves smelled like vanilla, and with a few and long interim breaks I returned a little more than a year ago. While coping with the outcome of the War of the Thorns, I ended up joining a group of adventurers that seemed to embody joviality through their hearty, relaxed and friendly conduct.
I stayed with them for some time and ultimately departed on friendly terms after adhering to a budding botanical benevolence, and so only fond memories now remain on that past forest path. It is not my place to say if it would or could be your ‘final home’, but from experience I can wholeheartedly recommend the Refuge of the Lost as a peaceful guild with a very kind and competent guild master.
