Greetings Adimu,
Congratulations on your success so far -- on your perserverance and all the stages you are going through! Those are all classic 'symptoms' that you have described!
You have a Higher Self or OverSoul that is definitely preparing you for non-physical experiences.
Sometimes at first the connections between the seven subtle bodies have to be loosened before we can exit the physical. Since your OverSoul is working on that now, it might be too early for an incarnated partner to assist you.
Do you have other preparation you can do during this time? For example can you adjust your diet to less meat, preservatives, sugar? Or maybe read more from spiritual adepts of the past? It might be that some such hidden concerns are holding you back a bit --?
I hope you'll stay in communication here and let us know of future successes and concerns! Feel free to argue out any ideas here that do not feel right for you!
Betson
