Jessica asks, “Please can you tell me about my spirit guides: Who they are, and their individual purpose for me? I would love that! I also would like to know what could help my father’s back problems, and possibly a bit about my dear friend T. Thank you.”

Dearest Jessica, you have a good number of entities with you now. You have with you a dearest grandmother being, one of great love; there is a great scientist that is always pushing you forward to discover the why and wherefore of everything.  You have with you a native being, one that often shows a type of lifestyle to you.  I could go on but you do not need to know who all of your guides are.  The most important is who you are.  This is much more important.
As to your father’s back, he is doing what he needs to do for it; you do not need to take responsibility for it.  Be there when it is important but perhaps I should say when he speaks a lot of this he simply needs your love.   Tell him how much you love him, always, and that he does not need a pain to receive it, that this is there always for him.  And as to T, trust that he is doing what needs to be done. You might be frustrated by this but accept that each being must find his way.
