extremely stressed

so hubby and I are about to close on our first home this week. we have been together for 8 years and moving out of our apartment. well 2 wks ago he lost his one and only client as he's self employed doing it work. we were pretty comfortable financially and now we have this stress. luckily I work but my income alone isn't enough for all our expenses. I try to not show my feelings because I don't want to add stress. also right before his client left him my hubby broke his thumb while doing work for them. because he's now injured I've been doing most of the packing on my own he helps where he can but I've done most and I'm working full time. well today we were both packing together and keep in mind I'm exhausted from work and stressed about finances and I said something stupid and he slapped me on the face nor hard but a slap is a slap. I let it go as I know he's stressed more than me but I'm not one to forget things and deep down he knows I don't forget. ughh what sucks even more is we were doing <a href="https://glowing.com/glow-fertility-program">fertility treatment</a> and now we won't be able to afford it 😓 and I'm 40 no kids.
