help on essay about donating blood.?
i have writers block,i did my introduction..came out very strong but cant think of ideas for the body.

please help?

either your introduction is actually not that strong, or you have no concept of writing essays.

your introductions should induce the point of your paper and give hints as to what you will be discussing (you’re introducing your ideas). So if you have a strong introduction then you must already have some ideas on what to write about. If you have writers block than your introduction is very poor.

What is your thesis statement? Infact why not just post your intro here so we can see your thoughts
