Lost connection with guides and angels

I have been communicating with my guide and angels trough astral projection for about a year now and whenever I ask for their assistence we use telepathy to communicate with each other in the astral plane but for the last 6 month or so I am not able to communicate with them anymore, whenever I ask them for help I don't see or hear them anymore as I was used to.

I wonder how this could have happend.

My mom told me that it might be because I have asked them too many questions and they simple stop responding to me as they want me to trust more on my intuition but I am not sure if she is right as she has not experienced any spiritual things like I have.

Today I projected and the only response I received was "aaaah" from my guide. It felt like he was annoyed.. could my mom be right after all?

Does anyone have any idea's how I suddenly lost connection with my guide and angels?
