Reading between the lines of what you’re saying, I can relate - I have a mind that didn’t come with an “Off” switch and sometimes I just have so much to try and clear out to be able to concentrate on prayer! :bounce: :whacky: I have ADD but I’m sure many non-ADD people have the same struggle to varying degrees.

But do not despair! God Himself wants to help us with anything that hinders us. He loves us - never forget that! So if you’re wrestling with those distractions or that sluggish feeling, send up a little prayer right then and there asking for help.
And don’t expect instant results - you may be blessed with immediate relief of the struggle but sometimes it’s a test of persistence. Just keep going, some days are better or worse in the spiritual life and that’s perfectly normal.
