When you file pro se, you are acting as your own attorney and it sounds like the case has gotten beyond your legal skills. There is no way to teach you to be a lawyer in a paragraph or two. If you are indigent, you can contact a charity organization like Colorado Legal Services to seek representation. Another less expensive alternative to paying a full retainer would be to hire an attorney on an hour by hour basis to review your case and help you with the documents you need to file in order to more effectively represent yourself.

You can file a document that advises the court of the mother's failure to comply with 16.2 and with mediation. You would serve yourself well if you scheduled a consult with a family law attorney to at least try to gain a greater understanding of how to represent yourself. It is a little like doing brain surgery on yourself.
It does sound like you may have some options for getting more time with your child. However, it also sounds like quite a bit has happened in your case and things have become somewhat complicated. Unfortunately, the best course of action can depend greatly on the specifics of each case. There are certain details missing from your question which could assist an attorney in helping you decide what to do (e.g. what is the exact status of your Motion to Modify? Often a court "grants" the motion, but all that means is that a hearing has been set on he issue).
Some attorneys, like myself, offer "unbundled" services meaning they will review your case and assist in preparing the appropriate filings. This is generally much cheaper than hiring an attorney to provide full representation on your case. There are also various organizations that provide free legal assistance to qualifying cases. Metro Volunteer Lawyers provides assistance on some family law cases.
Please remember that legal matters are complex, and that even the smallest details can have a great impact on a case. It is always best to meet with an attorney in person to discuss the full details of your case. Furthermore, remember that I am not your attorney until you have been to my office and we have both signed an agreement.
