I feel broken sad and lost.
What is your reason for feeling so sad right now?
I feel like I'm not living up to my full potential and that I miss great opportunities.
Everyone feels down about themselves from time to time, but you shouldn't let those feelings consume you. You should try to think about yourself in a positive light. Thinking positively will help you feel better and make you more confident.
I think I can't be fixed. I better end my life.
If you feel at the point where you want to end your life then you most likely feel so overwhelmed it is difficult to even think. Trust me that when you have someone help you sort out your thoughts and release some of the pent up emotions, you will feel so much better. Just allow someone into what is troubling you and you can have release.
