Hi. I am really sorry that your relationship has brought you down rather than becoming a need fulfilment in your life. You really need to connect with a professional on a regular basis and get the help required to help take a decision
Next Steps
You need to meet a psychiatrist and have a detailed discussion about this stressful life situation that you are in. He will assess for anxiety or depression or any other fall out of this life stressor. He will recommend therapy and medication( if the situation requires it).
