It's good you mentioned how you are feeling to your dad, if the feelings get worse you should definitely contact your doctor.

I can sympathize a lot wi what you're going through. I'm in a very depressive state right now as well. I'm also a highly creative person but when I'm feeling like this I don't have the motivation or patience to sew or draw or paint or whatever. Even if I try I just give up really quickly. Anyways just wanted to let you know that someone understands, sometimes that helps a little bit.
