An air carrier Flight Attendant reported an inflight fume event during cabin service. Reporter experienced physiological symptoms which caused her to vomit twice during taxi to gate.

Narrative

During service I had a strong odor in cabin and felt dizzy and lightheaded (note: I have been having these symptoms for months so I'm not able to tell if they are related; I'd assume most likely not). I told the #2 I would most likely write a [report]. I have been going through conflicts with my Manager and she recently informed me that she was going to reprimand me after I wrote a report for passenger misconduct (passenger continued to harass me after I told him that I couldn't breathe [because] I was having difficulty wearing a mask). Thinking about recent events with my Manager (and past incidents where I was also heavily interrogated after being severely harassed by coworkers) made me scared to file a report for the odor in fear of my Manager and/or crew members. During final descent (FWD facing jumpseat) I looked down the aisle; felt light headed; clammy; short of breathe and like everything was funneling in. I left my jumpseat and puked in the lav after landing and during taxi in. I came out to disarm my door and then leaned myself on the jumpseat to compose myself. At that point I heard the #2's phone make a sound like she was snapping a picture. I went back into the lav and puked again. I do not remember bits and pieces; especially as I was leaving the plane and jet bridge.
