I, 19F, am healthy, have no hormonal imbalances nor am I on any medication. I have not lost weight nor changed my diet drastically. I have seen some posts with this same question but the answers are kind of the same (they all suggest it is because of changes to the things I listed above).So considering that I have not gone through any of those changes, I don't understand why it seems my breasts are decreasing

I feel like they have become smaller compared to 2,3 years ago, and have gone down from 38 to 36 :,( I really don't know why and I'm naturally worried because I want to maintain my size. Please suggest why

I'm an angela main, so I always prefer playing support, but I understand that sometimes a tank is necessary. So how do I know when is the best time to choose support and when to choose tank? How can I tell which role my team needs, depending on the heroes they or the enemy chooses? Please advise 🙏🏼
