If you aren’t very confident in your own abilities to connect to your Guardian Angel, or doubt is overpowering your belief, then this is also an option.
If you find a medium that really works for you, it can be a great way to get in contact with your Guardian Angel. The medium will also be able to offer you extra insight into the problems you might be facing and how to overcome the challenges.
So if none of the other methods have worked for you this is probably a very good one to try, especially if you’re really struggling to get through a difficult situation.
