Bi-RADS 3

As Ingerp said, with a BIRADs3, the Radiologist has assessed that the risk that this is malignant is less than 2%.

The reason a 6 month follow-up is suggested is because what the imaging showed is most likely to be nothing, and because even if you are very unlucky and fall into the 2%, there is little risk to wait. Most breast cancers are slow growing and have been in the breast for 3-5 years, some as long as 10 years, before they become large enough to be detected. In that context, 6 months isn't a concern.

The way to get through the 6 months is to decide in your mind that this is nothing, and to consider the 6 month follow-up as being when this will be confirmed. I've had lots of 6 month follow-ups over the years and that's how I've always thought about it. None of mine ever turned out to be anything, and I've always been grateful that I avoided an unnecessary biopsy, which comes with a lot more stress. I've had enough biopsies over the years that I trust that the Radiologist knows when waiting is okay (a BIRADs 3) and when a biopsy is necessary (a BIRADs 4).
