Do be careful of your back like Mavis said! Do you have a garden? Even if the weather is shite and you can't be arsed getting dressed grabbing a coffee and sitting out for ten minutes for a low effort change of scenery might be nice as a stepping stone to a trip further afield.
Have you seen the GP and got meds. I have recurring depressive disorder and it's a real so of an illness. I totally get not wanting to go out or get out of bed. It takes me till mid-day to get up. On bad days I don't go anywhere and when I'm ok (which isn't very often) I can go out and about. Mind I've sat about so much that I have aches and pains in my hips and back. I'm 72 and this is my 7th year of enduring this illness. I've tried all sorts of ADs - none really work. It has changed my life SO much - I used to be out and about all the time with loads of energy.
Sorry you are having to be job hunting as it doesn't sound like you're up to it. Are you on JSA - if so it sounds like you need to be on ESA. Have you got any support in RL?
I'm like this at times. It becomes overwhelming and then I can't find my hairbrush and then I can't find socks etc so I don't go but since then I have told myself it doesn't matter what your hair is like or even if your in your pjs if you are popping out for a pint of milk/can of coke/chocolate bar just a garage or corner shop. People do it all the time. If you tell yourself that it might make going out easier. Or walk to a post box and back, then you don't even have to talk to anyone. It makes going out the next day or dat after a smaller hurdle
I have to go out tomorrow, I have an appointment. I do tend to be able to manage when I have to do something.
I send a relative to shop for me.
I do wonder if it is why I fucked up a job interview at the beginning of the month...a friend gave me some advice and remarked people can tell a mile off if you are down / depressed in a job interview. Oops.
