I have no great words of wisdom, but I understand the feelings. It sounds like you are not seeing anyone right now. Can you make an appointment with a Therapist and a pdoc? Tell them how you are feeling. If it's nessasary do you have a place you can go for an emergency? Here in the USA that would be an emergency room, but I don't know the equivalent where you live.
Take care of yourself first,the rest will follow. Sometimes it takes a while to find the right therapist and medication that really helps.
