Not much success lately! Any Help Why?

Hello everyone! For awhile I had success getting into the astral. I have my own technique that works well or (worked well)

For the past couple months I have been undergoing a lot of internal and external change and I wonder if this has temporarily blocked my ability? By all means, I didn't perfect the technique but I was getting a good success rate until recently. Do you think this is a mental thing? Have I been too focused on the material world? Have any of you felt the same way?

Thanks everyone!
