Galatians 6

Galatians 6:5

For each one will bear his own load.

 Normally, I try to avoid bringing other verses into consideration for this writing, but this kind of confuses me.  A couple verses earlier, Paul instructs us to bear one another's burdens.  Then here he says that each will bear their own load.

Is there something in the terms used that distinguishes the two?  Or are the verses in between giving some kind of context, regarding self-examination?  Perhaps there is a change of topic between verses 2 and 3, where 1 & 2 are about restoring and supporting one another, and 4-6 are about being honest with oneself about what you have done and what others (like Jesus?) have done for you.
