I am a lot like you in that I try stuff and dont feel anything. The thing Ive learned is that everyone is different. Some people are just naturally more phychic and can sense things much more easily. Peple make the mistake of thinking that what works for them will work for everyone else in exaxctly the same way. But I have slowly become more sensitive to things. It takes time to develop your skills if you are not naturally phsychic. But I did decide to banish doubt and unbeleif using a ritual which really helped. I also anoint my forehead with frankincense which is good for activating the 3rd eye (for me anyway.) So it will take time for you to develop-beleive me, Ive been there!
Why dont you try using angel cards? They work whether you are phsychic or not. You need to do some protective rituals and first just to keep the nasties away. I always connect myself to God and then channel his energy while I am shuffling them and then pick one out. Use a deck which is relevant to the type of questions youre asking i.e. it should have the type of cards which can be used as answers to the type of question you are asking.
You can ask angels as well but it is important to protect yourself as Ive heard stories of bad spirits guiding people.
As for bad things happening, Im still pondering on that one myself!!
