My Husband Will Be Losing His Job By The End

My husband will be losing his job by the end of this month, although he has a severance package that will continue his pay til the end of March of next year. He is understandably stressed about this. He is 60 yrs old but looks 10 years younger. That's one part of his problem. He was fortunate enough to have worked for his brother in law and has finally made a decent salary for the last 5 yrs. I have always had the opportunity to grab overtime at my job so I figured I'll do it while I still physically can. I'm a letter carrier for the Postal Service for 20 yrs. my husband currently works for an X-Ray manufacturing co. That is moving to China. He has worked there for 17 yrs. I'm his 3rd marriage. His 1st ended in a divorce( his wife had cheated on him). His 2nd died of cancer. We're married 19yrs. We bought my uncles hse that basically was outdated on the inside but had a good layout. Every or every other year through the years we have put money into fixing up rooms but he is still unhappy with our house, claims we got ripped off. I usually work on Saturdays and when I get home we used to go out with friends either go to theirs or our house for a get together or meet at a restaurant for dinner. But since he is losing his job, we have been socking away $$ in case he can't find another job. We have 3 years left on our mortgage but also have a line of equity loan. We also have a grandson that is 2 1/2 yrs old that has brought a lot of happiness to us both. My husband was very depressed when I got home tonight which he has on occasions B4 so he went to bed at 6:30. 6:30 on a Saturday nite?? That's his way of dealing with it... He has a realistic/pessimistic attitude. I tend to have a positive attitude towards things. I've asked him in the past when he gets like this is about me but he says no. He just hits a wall and can't deal with when something breaks down in the house I tend to want to resolve things and acknowledge his feelings but sometimes he makes me angry the way he deals with things. Usually after he wakes up the next day he feels a little better. I wonder if it has to do with his testosterone level decreasing. Got any suggestions??
