Feeling Empty and Depressed

rant/seeking some love: i've felt really really depressed the past few days. like i've just felt completely empty. i always forget how much i despise this feeling and how powerful it truly is until it comes back. today was really bad, my flatmate came in to check on me because she knew i was feeling low and i was laid in the darkness doing nothing. i did manage to get out of bed and go with her to get some chips which helped me but she said that it was really scary seeing me like that and so sad. i completely understand and it's scary for me too, i get so scared whenever i'm in this state and scared for other people to see it. it's left me with my mind racing, i don't even know how to word my emotions or what state i'm in now. i still feel empty and like my soul has no light in it but i feel wrong to say i'm still in an depression episode because i'm not as low as i was earlier today. does anyone else get this feeling? or provide some reassurance about these thoughts and states?
