Colorado is an "at will" employment state in which you can be fired for basically any reason or no reason. However, there might be an issue as to whether you fall under the Americans with Disabilities Act which would provide you with protections. Additionally, the Family Medical Leave Act might be applicable as well, although it is hard to tell. Finally, you might have an age discrimination case under Title VII is you can prove the termination was due to age. A great place to start is with the EEOC and the CO Department of Labor.

Yes, they can fire you. Mr. Leroi's analysis is right on.
In no way am I offering you legal advice, and in no way has my comment created an attorney-client relationship. You are not to rely upon my note above in any way, but insted need to sit down with counsel and share all relevant facts before receiving fully-informed legal advice. If you want to be completely sure of your rights, you must sit down with an experienced criminal defense attorney to be fully aware of your rights.
On what basis were you discriminated against? If the real reason you were terminated was because of customer complaints or sales performance then you were not discriminated against and you have no claim.
If, on the other hand, you believe you might be able to prove that the real reason you were fired was because of your age, your race, your gender, or an actual disability, then the termination might be illegal. If that is the case, you need the assistance of an employment attorney.
