Hi there. You definately seems to be depressed...
See you have gone through a lot I can understand that and your brother whom you love is in prison. I have also been through a long depression for about 1 year .
The reason that you dont want to do anything is coz all these thoughts are coming in your mind. You might have heard empty mind is a devil's workshop.. Try keeping you self busy. Join some sport or anything of your interest.. Never sit idle bcoz this will again prompt you to think about bad memories. Ok..
And please never think of suicide..This is a literalally crime and what happens after you die un natural death ( you dont wanna knw)
see your brother is in prison is bcoz its karmic (things he did in his previous birth) instead on lying down in ur bed and thinking that what iam I going through..Pray for your brother...Make it a routine ...
The key is keep your self busy...
If you want to share anything that will take burden off you shoulder just pm me.. Ok..
Take care and god bless
