Oh you poor thing.
I was in a similar situation last year, major anxiety and depressive spell and I hated DH, really hated him for a time. Almost all of this was due to the depression, I would make an effort, huge to me due to my problems, tiny to him and then get so cross that he hadn't noticed. Things like just resting my hand on his chest was such an effort and then he rolled over or something and I would feel totally rejected. I'd then start fantasising about running away, divorce or suicide.
My advice would be:
Talk. Talk talk talk to him, but try to think about what you want to say carefully. Invite him to offer suggestions e.g 'love, we only have x in the bank account, where should we go from here etc' was much more productive than the bile I spewed at him when I was at my worst, with loads of snotty tears. Perhaps together you can come up with a plan.
Touch him. Not sexually unless you want to but just kiss him on the cheek or brush your hand against his once a day, increasing over time. I realised that I was expecting him to behave a certain way but not encouraging or doing my bit, just freezing up or mentally assessing him against my 'ideal'. I read a lot of erotica to get me in the mood and to try and restart my sex drive a bit.
Try to get away somewhere that makes you happy and (woo alert) lifts your soul a bit. The beach is what works for me, or woods. Quite often DH and I go with the DC who charge ahead so we can hang behind and hold hands, chat or just be quiet together. Cheap too, usually costs us nothing. Perhaps you could go by yourself and have some peace to think.
Try and eat and sleep. I remember what it's like, I really struggled with this one, but when I finally had a full nights proper sleep it improved my mental health and perspective enormously. Eating proper meals at the proper time helped me sleep too. Lots of water too, dehydration really affects my concentration and anger levels, as does too much sugar.
It took a long time, eight months, but we're back on track now, but I had to put a lot if effort in to address my thinking. We did a lot of talking and he had ideas and plans I had never even considered. Also I didn't realise how much my unhappiness was making him unhappy too, he had noticed but had no idea how to help. Talking allowed him to see how I was thinking and he made the effort to help me too.
I really hope things improve for you soon, someone wise once said its always darkest before the dawn.
