How to help Husband?

So I'm a sahw and I do everything I possibly can around the house. What I need help with is how do I help my husband. He works from home right now and he goes in at 9am and supposed to get off at 6pm but sometimes works late. He just got off at 730pm and I asked him why it took so long (I was a little angry but that's besides the point). He then broke down and says he has issues. He says he can't concentrate all the time and then gets upset bc he can't concentrate. Then when he is able to concentrate he works until it's done. His other issue is he's scared to ask for help bc he feels like he should know it even though he still some what knew (been here almost a year). He also has a hard time telling me his problems and he knows he can come to me and I'll help him the best I can.

He works in our computer room and gets up every morning at 830am to go to work at 9am.

I just want to know is there anyway I can help him with this?

Also how do I get him to communicate more with me about his problems/worries like I do with him?
