I don't know what you're thinking or going through. I'm sorry if something terrible has happened or is happening. However therapy or personal counseling is exactly what I would recommend. I was annoyed because I felt exactly the same way at one point. I felt so useless in the world, only thinking about the negatives.
I want you to come back and you're right I don't have all the answers. But after being stuck in my dark room for 2 years, I realized learning is important and something I still want to experience. I have had so many panic attacks just doing my work. I was sent to a hospital for one. Your mindset is what will help you live on. Please take some time to relax. Try new things and find something you enjoy. If you are still here, please talk to your doctor about this. Certain medications have bad interactions with other medications. I consider you as a friend, a lot of others probably do too. But I am just trying to help that friend, not force.
