How can I feel focused and alert? Please help.?

get rid of the drugs. Get consistant exercize, go for long walks.. Focus more on helping others, it will take your focus off yourself. Realize that everyone gets stress, lack of consantration,anxiety and even depression, even Jesus Christ did. Dont think of these things as genetic, that is for losers. Think of life as your ability to control and change your behavior and life, one decision at a time. This is one thing that seperates us from animals. Little things , every decision toward a goal mean alot And spirituality , especially Christianity is most important.
