Just get them to sit around and they will get better. (but they still have to go to school).
no
No.
go to bodyshop and make a sim and then import!
Your sim is either pregnant (if you have Sims 2) or is ill with the flu (usually you would get a pop-up telling you this). To stop them throwing up make sure they rest by lying down on the sofa or bed and are off their feet until a pop up appears saying 'Your sim is healthy again'. If your sim is pregnant it will stop when they get their bump. Hope that helped.
Yes you can make yourself a sim in the sims 2.
You can't make a Sim beg for money.
You can't make your sim an actual ninja. However you can make you sim look like a one. You get "ninja"- like clothes in the Open For Business EP.
Sim + Tombstone + Mourn Interaction = Crying Sim or you could break a Sim's heart by terminating a romantic relationship, killing a Sim close to the Sim close to the crier.

Sim
Oh, what a happy little question! In Sims 2, you can create a new Sim that's not related to any other Sim by selecting "Create a Sim" from the main menu. From there, you can customize their appearance, personality, and relationships to make them truly unique. Just remember, there are no mistakes in Sim creation, only happy accidents!
