I'm sorry for what you are going through. I can relate that. Sometimes circumstances are not in our favour and we feel miserable. All I try to do is to avoid using worthless words for myself. Instead say I'm great, I can handle everything. Though these words will seem ******** to you for the moment but they can console you to some extent. When you feel low and also condemn yourself, you wish to just kill yourself at spot. We make ourself feel worthless and just we can make ourself feel worth living.
Wish you well...
