PS. i came up with a spell but I don't think it works. Could you try it and/or amend it please.
Premonitions are what I ask,
Future knowledge shall be unmasked.
Premonitions to help me see,
What the future has in store for me.
I know its weak and pathetic, but its the best i could do.
ANY spell you've written yourself is a thousand times more effective than using someone else's, no matter how pretty they may be.
Now create a little ritual around it, light a candle, use a basin of water, a mirror perhaps or a crystal to focus on so you can "see" your premonitions on a screen. Keep practising and you will get better, absolutely.
As to the guardian angel/helper spirit, go https://dragonrising.com/downloads/ and get the 1st Sanctuary meditation.
If I remember correctly, there is a guardian spirit being called in there, in a safe place and in a safe way.
Develop your relationship from there, and once again, it's a case of regular and often to get higher, further and deeper.
