It is just too much :S

I am not sure why but I don't seem to be able to handle things very well these days. I just think too much, I can't take small responsibility. All things seem to be very overwhelming and I can't rest. I worry about everything and anything under heavens. I have given it all to God but things are just the same. I am way tired and frustrated. Some things are just not genuine worries. I felt I have just been worrying too much and I can't help myself. Tried to calm myself and relax but it just won't work. May be this is just a sudden change of lifestyle but the worry is taking its toll on me.
