Was my nice managwr got fired?

So my manager was nice all the time. Never seen her angry was smiling, positive person. As I asked her 4 months back would she want to go to other departament to be a manager or just change position. She said no she likes it here. So it didn't sounded she is to much a career wo. an and she always used to come to work 5 minutes before work. So not lije workaholic and used all her holidays for travel. So one time i heard her saying to other manager sad life and other manager asked did was weekend enough for her to get over her emotions. One time i was surprised when we had lunch and she just came to talk with my team from no where because mostly she never had lunch with us or come randomly to sit and talk with us in kitchen. After few weeks in team meeting she sais she is leaving the company because she found a job what she worked in usa and she wants to try and helping patient, but when she already worked in pharmacy company helping patients makes no sense so after she said she is leaving she seemed there was no smile in her face, seemed worried. Some said she even responded more like angry and even to me when she was so nice all the time. She did not added anyone on facebook after she left, during fairwell party she spent only 2 hours and i think left to other party and heard she said to other manager she is planning to get drunk and is leaving for holiday although she was just before that. Do you think she was fire?
