Moving forward in life doesn't seem possible for me anymore.
I'm sorry to hear that. What do you think is making you feel like you can't move forward?
Both metaphorically and literally, my vision just won't improve and I've given up. I'm just gonna end it.
I don't think giving up is the answer because I know you'll be able to figure out these feelings. It's normal to not know what you're doing in life and not be sure of where you're going. That's all part of life and if you need to get some help in figuring things out don't hesitate to do so.
I don't think you understand.
I'm not sure if I understand fully, but I know that giving up isn't the right choice. I really think you would benefit from talking to a therapist about what you're dealing with, because they'll be able to help you.
