I notice that when my depression is the worst, I feel more empty, numb and detached. Its like everything is blunted. Almost like I'm wrapped in a bubble of dampening space. (I know, strange). It can be very scary to feel that 'apart' from yourself.
I find that when I feel this way, I tend to just want to sleep. Sometimes, though, if I have the energy or guilt, I will accompany my husband to walk the dog. After the walk, I feel a little better. Just getting outside in the sunshine can lift my mood some.
I know it's a small, simplistic thing, but it helps some for me.
Also, I know that staying in bed tends to make me absorbed in my phone, and further increases my sense of isolation. Except when posting here! Good luck all
