He sounds extremely depressed. I know for a fact it is hard to understand man's existence let alone the hope of being with the Lord.
@Apache1 Please go find someone to talk to. It is almost impossible to see that life may become better again, but it can.
I am not the only person on this board who has been through severe depression. It can get better.
You have a Saviour who understands what you are going through. The Lord has provided for His people doctors and other health professionals to help us when we cannot help ourselves. It is not wrong to get help.
Please try.
