Baby shower! Advise needed!!!

So I’m going to try to make a long story short, so bare with me because I really need advise.

Since about 15-16 days that were suppose to be about me (birthdays, concerts, etc.) were always taken over by someone else and I got over shadowed. Happened at my open house, birthdays and wedding.

So my best friend is planning my baby shower and it is suppose to be about me and the baby (and hubby if I were having a coed) I have a feeling that it will happen again. (Usually by different people at different events) How do I put my foot down and say it’s about me?? Before I would just let the person over shadow me and I would either hid or just get lost in the crowd, but I would always feel horrible/ anxious/hurt and disappointed.
