OLC, you can't just dick about with AD FGS. Prozac for 2 days won't do a thing, it takes a good couple of weeks to kick in, as do most of them.
Depression is a serious, life threatening illness.
Go to the Drs and tell them you need medication, that you don't want to put on weight and what your symptoms are, ie are you anxious, or lethargic etc. There a million AD drugs out there, one will suit you.
Have you tried CBT? Cognitive Behavioural Therapy? it saved my life, teaching me to slow down, stop and challenge panic/black spiralling thoughts and highlight the truths. No-one thought I'd survive, not even my own therapist. I saw her notes, they fully expected me to die.
10 years on, I'm still here! Come on girl, you can do this, take a deep breath and really challenge these thoughts you are having. Your DH is entitled to watch the telly, if you want to cuddle him, go and sit next to him, hold his hand. Don't stand there pouting that he won't get up and come and cuddle you... Go to him.
Give HIM love, give him affection and he'll give it right back. You are very defensive/prickly at the moment, but it's the depression doing that, not you.
Take the YOU inside back, fight the depression. It can't win, it really can't.
