It is very unfortunate that some coaches are like that, I myself was asked multiple times to change coaches! It is also very sad that your own team is not supporting you even if you are not taking Shakeology...this is not right.
But...we are not all like that! Some of us have people's best interests first

Like CoachMarch is saying, stay positive...Beachbody is a wonderful community.
As far as supplements go, you definitely need proper nutrition

You can do it!!!
