Psychic Armor

You helped me before with a dark entity, by pointing me in the direction in which to take to fix the problem. I have a new strange occurrence in which I think this is the perfect place to go for answers.

I am using a standard protection shield from negative energies on a regular basis. For a long time I was attack mentally and taught myself how to create a bubble to prevent most of it.

The other day I was being targeted by a particularly nasty psychic attack and my bubble was FAR to weak to handle it. I asked for divine assistance and within 5 minutes I could feel my arms wrapped in psychic gauntlets. They were incredibly strong and I actually felt myself being weighed down by them physically. I had been wrapped in a full suit of armor, I could almost see it and just knew it was there. I was almost giddy with this new sense of enpowerment and security washing over me.

Ever since that day I have been able to call that same armor back of my own accord without asking for help and am curious as to why they feel so heavy. It is like I am wearing 5 pound wrist weights. Is it a lack of ability, am I just feeling the weight so I know they are there, or have I stumbled onto something I should leave alone? I have grown used to them, and no longer get giddy. I also only call on the armor when I feel it is necessary. Is there any special name for the ability? Please give me guidance on the matter. I would rather not disrupt the balance of my mind if it is a bad thing to use the armor.
