Meaningless Weekends

When you reach one point where there's just nothing to forward to in life, what do you do? I mean, whats stopping me from ending my life? I just realised that, I would look forward to the weekends but when the weekend comes it'll just be like any other weekend, same routine, i keep thinking that i'll do something different this weekend, try to do this and that but it'll just turn out to be the same, it's so meaningless, life is so meaningless actually. I don't accomplish anything during the weekend, i don't accomplish anything during work and studies, I practically stopped accomplishing anything in life. I wish i could see life full of colours and joy but in reality what have life been giving me?
