Thank you for sharing that with us. Of course this is the right place to do this. Please know that this is a safe space for you to share as much as you like about what's on your mind and how you're feeling. Don't ever feel like you aren't allowed to share. Writing out your thoughts in a journal can be very helpful, but venting to someone and having them listen is very valuable as well.
It sounds like you're really going through it right now and that you're thinking very low about yourself. How long have you been feeling sad, dysphoric and tired? Do you feel that you have a lot of days where you find it hard getting out of bed?
Have you ever spoken to a professional about what you've been going through, or considered seeing one?
Please be patient with yourself - I know it's hard and it's not easy. Let yourself feel what you need to feel, and take small steps to take care of yourself, even if that just looks like going for a short walk, drinking some water, having something to eat. You are not a disappointment.
I hope to hear from you.
