I'll be honest with you, even during my strong periods 'in the truth', I never really thought that god heard my prayers. I used to delude myself into thinking that it was the same for everyone. As an example, I had several opportunities to further my career and make a lot of money, while telling Jehovah that I could work less, and do more ministry. Basically, I could make a fortune on commission, and have triple the amount of time available to pursue theocratic goals, and contribute a lot to the KH fund. Absolutley nothing happened.
I've had to put up with friends sending me to coventry, and family giving me the cold shoulder. I can't say that I wasn't bothered by this, as, like you, I knew fully what to expect. I'd say it's just plain old depression that you've got. You need to fill your life with interesting things to do. Meet new people, and realise that 'worldly' people are just people. Originally, when I left I had this idea that I wasn't going to associate with worldly people. I needed to just get in touch with reality.
I can't advise you of spiritual things, as I'm now an atheist. However, I really do marvel at life, nature, our planet, and how damn lucky I am to be alive. I like to read books and watch programmes about nature, history, science, anthropology etc, and it's enough for me. I live in a really beautiful part of the earth, and sometimes when I go out for walks in the mountains, I'm left breathless at the beauty. Maybe you can find your spirituality somewhere else other than a book.
If you want someone to listen to you, just come on here. Some people just rant, and it does them a power of good
