I'm with you on the suffering in silence bit, but i've found things better ever since i've had the support of my support worker.
I'd probably lay off the sad films, even though thats hard, i know when i'm like this, i listen to sad songs, i'm not sure where the sense is in this, i suppose i feel "if i'm so down i may as well feel it properly."
I'd probably speak to your SW about the part you're unsure of.
Try and get some sleep as well.
