Help hubby has been unemployed for 6 months and have not had in about 5 months.?

My husband was part of a downsizing were he worked 6 months ago. He has been looking for work and been on a few interviews but so many people looking right now that just has not had any luck. I can tell this is making him depressed luckily I am still working so we are able to get by barely. This depression has caused our life to disappear. I try to make him feel better and boost his confidence but doesn't seem to help. I have done just about all can do to try and get him out of this ual slump and nothing seems to work. Just the other night I came to bed completely naked and tried a little oral stimulation but he just did not respond.
