I'm losing control!

I feel like I'm taking care of the world. Some how, at the end of the day I feel as if everything falls on my head... and usually I'm proud about that. But now, I feel so overwhelmed... I couldn't even do something necessary for myself! And I know, people say that I should distribute the jobs and not do it all myself, but I feel as if things won't happen and progress that way! Am I a pushover??? What should I do from here? I general, how shall I act so I won't end up dead nervous and out of control with my own life?!

You should be proud of the fact people rely on you and count on you. But sometimes to much is enough! Dont take on the full workload yourself share out the responsibilities, and know when to say no! dont let people step on you and take advantage of you, tell them what to do for once and be on their case until it gets done! people can look up to you and learn from you, you just need to speak up.
Good job tho.
