I know it can be very frustrating when reading yourself and trying to be objective.
I wrote about this here:
Six Mistakes To Avoid When Reading Tarot For Yourself
As far as the same cards coming up again and again in a reading, I believe that there is a message that you cards are trying to “tell” you.You should try to record that reading in a journal or even on your phone so you can look back on it, over a few days, weeks, months and see if you now have a better understanding of the reading.
Let me know if you need more guidance after you put these practices into effect. I’d be more than willing to help. :)
