This is so powerful and I get exactly what you mean:
good friends well they help a little, make us laugh but never so much as to make the sadness go forever,
hugs subside the sadness a little but again never enough,
food well it helps but then because we have eaten crap we feel bad, so in all fairness it helps whilst we are stuffing our faces and then bam the realisation of what we have done makes us worse...
The image of sadness yes telling through your veins and being an essential organ is very powerful and somewhat overwhelming as this was tinged with so much emotion and sadness I was left feeling breathless again and it make me think how when we are this sad we so cope and learn to live with it.

Fantastic write which will be nominated by me when my votes are back.

Edit: I also realise that even though we are consumed with depression that no one can ever completely understand how we feel (even those suffering) because each person with depression has their own situation that made them become this way.
I would also like to apologise for rating a 4 my phone froze as I clicked. Defo a 5/5, sorry.

Soul sadness.

<3 you.

YES. I feel you and my heart aches, too.

Love you lots.
