Help - Anxiety attacks after a break up

Can someone please help me?
I have broken up with my partner after quite some time - I moved to a new state for him and now its all over..
I have had two weeks off work - holidays I had organised before we broke up -
Im due to go back to work and I cant bring myself to leave the house.
I have spent the last 2 weeks in my house, crying, trying to sleep but not being able to, feeling sick, feeling like Im kind of going a little crazy.
I am crying at the drop of a hat - sometimes for reasons I don't even know.
I can not eat - a dry cracker a day every few days is the best Ive managed to eat.
I feel emotionally numb
I don't want to leave the house - I don't want anyone looking at me.
I am nauseous
I seem to have to go to the toilet a lot too even tho I am not eating.
I cant sleep - I wake up every 30-45 minutes
When I go to leave the house - I start to feel light headed and dizzy
I cant bring myself to do anything..
Even taking out the trash is a big deal..

Can someone please help?
