Give up from what? With life? Its not just you who's been thinking about giving up in life. I suggest that you should sleep first to rest your mind from over thinking then see if you still want to give up. Why don't you eat ice cream or chocolate? It helps people with depression or stressed out. It does work for me. We human gets tired often times. We get tired from so many things about life and all we need to do is to breathe out the negative energy inside us. Leave for a while. Go to a place where you can have peace of mind a park maybe, beach, farm or even carnival. Be childish its okay. Help yourself, talk to yourself and listen to yourself. Most importantly love yourself.
