feeling useless

can someone please slap me! u noe i came to a realisation last weekend that the reason why i feel lifeless and lethargic and horrible half the time is because i'm actually feeling USELESS! coz i'm lazy... dont wanna do my work... putting everything off... and then not feeling good coz i noe im goin to face trouble coz of my laziness... but YET im still not doing anything about it! i discovered that after i finished many maths question frm my holiday hw on sunday - the day i wasnt allowed to go out and i sat at my desk and did maths the whole day - and woah the difference i felt after that was superb! I FELT USEFUL AND GOOD! (even tho i couldnt manage lotsa questions) yep ok anw the thang is, right now, i'm feeling USELESS again. coz try as i may, i'm so damn lousy at maths. i cant do almost all my work and it just leaves me so ARGH!!! and the lit essay's beckoning but....i cant even anotate it properly. u noe how frustrating! like u're trying but u're somehow so stupid u cant even help yourself! osigh osigh! ive always believed that tuition is crap coz everything is up to u ta put the effort in! if you really try, you can n u will do it! but apparently NOT! looks like i'm pretty hopeless at maths... really... oh shit....
