Not sure what to do

My husband quit his job like 3 weeks ago he's not looking for a job. We have nothing for the baby and I have 3 months till he's born. I'm working 9-12 hours 5 days a week. My 3 year old has to get his second set of tubes. I have to find a way to get everything me my 3 year old son and this little boy need. I still need a crib swing car seat everything! I'm always tired and now my Dr is talking about bed rest which I can't afford! My baby shower is September 20th and I'm due 3 weeks later. I won't have anything ready I'm stressed to the point idk what to do anymore! Any advice would be helpful just please don't be rude about anything said! I'm in need of good advice.
