I feel lost in life too. I may not be qualified to give advice on this topic but it is important to realize that you are not alone in this feeling. Also I think you should make a list of reasons (on paper or an electronic copy) of reasons why you feel lost. Once you identify why you feel lost, you can start to conquer this feeling. But conquering this feeling may take time.

Just realize that everything doesn't have to be perfect today. Just take life one day at a time. Don't rush life. Just hold on. Keep reaching out for help.
