The good news: all of this is fixable. All of it.
Step one: if you're this overwhelmed and it's been going on a while a trip to the GP is probably a good idea, you might need some meds to keep you stable while you go about changing things in your life. You might also need signing off work for a bit. Go book an emergency appointment and talk to them.
Call the employee assistance program again. First because it'll help you offload again, which keeps you going for now and second, because there may be some kind of system whereby if you keep calling them about the problems it triggers a referral for further help.
Go on the money matters forum here and ask for someone to point you in the direction of help for debt or give you advice. The sooner you can pay it off the sooner you can stop worrying about it. There will be a way even if it takes a while. Just making a plan for how to deal with it will make you feel more in control.
You're not in the right mindset for weight loss right now but know it can be changed in the future. For now eat plenty of vegetables because your brain needs nutrients and take some kind of exercise daily, just a walk round the park is fine because being outside, even at night, even in rain, even if there's not a blade of grass in sight, plus the exercise itself, will help your mind.
The viruses and breakouts could be stress. All these measures to tackle your MH will improve that. Get some echinacea tablets and take them 10 days (no longer) to help give you a boost to get over whatever you've got at the moment.
Grab a notebook and pen, write down all your thoughts. They don't have to make sense. You don't have to read them again. It's to get them out of your head right now, that's all. It could help stop your mind going round in circles endlessly. Afterwards you might be able to sleep.
Instead of moving somewhere right now, wait until you've paid down the debt. For now look at furniture/storage solutions from IKEA or somewhere, to make your home work better for you. Then search out second hand stuff to keep costs down or DIY your own version.
You'll get a new job one day but probably need to tackle this other stuff first, to get more stable mentally and healthy physically and to gain confidence in yourself that you can achieve things.
There will be times you can't do anything much except maybe shower, care for baby and go to work. That's fine. Don't beat yourself up about it. Do what you can, when you can and it'll all eventually get done and life will be better. Don't get caught up with having a perfect home, schedule some time to work on these life improvement things even if it means no house chores get done that week. You'll get there.
Also find the number for a MH helpline and call it daily if you need to.
