I agree ((((canders)))) you can't continue like this. You NEED to eat properly and you NEED your sleep, to begin with. Make those two things PRIORITY in your life, ok? No thinking about them, no wondering if you're worth it... by not providing them to yourself you are engaging in passive suicide, imo. Stop.
You need to limit all of what you do. Can you do a different job for the same place? Something that limits your contact with others till you begin to feel better? You had a good morning! I'd take that.
You are overwhelmed... I know you said you don't know what to do... so right now just stick to the eating and sleeping goals ok?
