I can understand what you mean by wallowing in one's own depression and have had many personal experiences with if but I'd have to disagree how or why I'm not sure but whenever I felt myself sinking somehow I was able to bring myself out by recognising early on, probably not even realising that I was kind of using a 'preventtion is better than cure approach'.
On the other hand taking on depressive energies is a mission on it's own because everyone is affected differently. And being HSP the subtlest amount is sufficient to make me feel like I'm being drowned and suffocated in it.
This past week by far has been the strangest on my empath journey I was under numerous depressive energies amongst other types, my telepathic connections and empathy were blocked almost. It's difficult for myself in the sense I don't really know how to raise the vibrations of the people these energies belong to or whether I should attempt at all fearing more harm than good..
Sleep wise I was consciously aware I've been having (sending/receiving) caliraudient messages, perhaps of all the people's whose energies I was under, upon awaking I was able to pick out small fragments of the conversations one of which was linked to a soul mate and and another that was perhaps prophetic?..
I kind of felt like I was asleep but not actually asleep, waking up tired and feeling as though I've not slept at all, somehow in a strange sense my own self was completely numbed out and I was being taken over by blackness that denoted again not in the negative sense but prophetic energies and I'm assuming it had a link with a chord I tried to cut with someone, not in its entirety but one aspect of it..
The moment I returned to the chord I was trying to cut I felt a huge burden lifted off of me, that I could literally finally 'breathe'..
I have no idea what to make of it.
And something really strange I noticed, I was watching a concert I think on Saturday and I saw the person facing towards me was not in they're own energies, how I was able to tell that I have no idea because I honestly was pretty much numbed out and all j was picking was really faint subtle energies, whether that was a mirror reflection of myself in a person (whether that's possible I have no idea).. they just didn't seem themselves, body language was different, eye contact was judgemental, composure didn't seem right, seemed withdrawn, careless..
Depressive energies overall of others for empathic people are very dense and absorb slot from others..
I kinda felt like Morticia from the Adams family over the weekend haha but even with the colour black I caught so many projections like the colour became a magnet for various negative energies I couldn't possibly count them all.. the next day I wore the same outfit again and I can sense so much negativity from it and normally I'll sense those energies from the atmosphere..
I know all of this isn't relevant in this thread but I'm working on a blog so don't want to forget all this and want to add all of it there in a more helpful way hopefully so I add bits now and again..
