I recommend poetry by W B Yeats, Keats, Shelley, Robert Frost and Emily Dickinson. You might enjoy C G Jung's autobiography Memories, Dreams, Reflections. You might find wondering around an art gallery lifts your spirits or perhaps you'd prefer a walk in the woods or near mountains.
When I left the JWs my spirit was starving for nourishment. I agree the idea that running microphones or giving out leaflets is somehow spiritual is ludicrous. The neglect of the people is, I agree, appalling. You would find volunteering for a charity much more rewarding. Your local library should be able to help you with volunteering opportunities in the area. Or just google it.
I understand the happiness that meditation brings. I was first taught it by Buddhist monks in saffron robes but the teachings afterward put me off. Western Buddhism is similar to Christianity. Personally I look for spirituality without religion now.
