Backstory. I’m a 35f who has dealt with depression/anxiety/ ptsd/ ocd since 11-12 years old.   
Last week it was discovered that my house has bedbugs, and we are in the process of fixing it.  I have not stopped crying in a week.  My ocd tendencies are starting to flare.  I feel so depressed that I can’t eat.  I sleep only when I pass out from exhaustion.  I’m running on fumes and I am weak. 
Things are on the slight upside but my husband isn’t always able to handle me at my downtimes.  He tries really hard! But I’m a bit too much at times.  

Can anyone help guide me to help feeling better?  I know it’s a lot to ask.  (If it helps- I am on medication but I nurse my youngest, it doesn’t do much- but I think it’s sort of keeping me down currently)
