I was just sick with covid for a week. just went to get tested & im negative. im going to a halloween party in a couple days. is it possible to get covid again immediately after recovering from it & testing negative?

Unless you had a positive COVID test there is no good way to tell if you had it. If you were + then you should self isolate for 14 days and mask up. You can check antibodies in a few months. Assume you had been vaccinated for COVID and flu. So should be no worries. I would still wear a mask and ask that others to the same. CDC warns do not visit Philippines unless vaccinated. Get the jab!

Continue to self isolate if you have any symptoms. A negative test indicates clearing of the infection, but 14 days of isolation is advised. Consider attending the event by zoom. A flu vaccine is recommended. You may have the COVID 19 vaccine in 2 to 3 months.
