alina, i somehow know how u feel @ this point. your posting was pretty much why i signed up for an account here in sajha. i've been thru this and can relate myself to you.
 i know it'll probably be the hardest thing you've ever done in ur life. but trust me...u'll get over it. try n be strong and keep working on ur life-goals....such as academic, financial and professional goals. these are the things why u came here initially, isn't it??? giving all up for just a boy? nah...
 i thought i'd die too when i left him. the pain was so unbearable but yet i made it. came out of that depressive state. u can do it too. keep believing in urself and working on your goals. imp thing is to stick to your friends, make some more friends and live your life.
alina, make him realise your no joke. not a timepass. everything said and done, make sure your doing it for you.
will take a lil time, but sooner or later you'll find out you can actually live comfortably even without him.

some tips: pamper self, try to excel @work/school, stay busy, try work-outs...it's very imp to stay in shape and look pretty...you'll get more compliments n hence will up your confidence. and do not(i mean do not) stay home cuddled up in bed....get out of that bed and socialize!!
