I've been feeling more tired and have some trouble breathing. when should i see the doctor?

Difficulty speaking: The most common cause of "difficulty speaking" is shortness of breath. This is usually a sign of serious illness including pneumonia, blood clot to lung, heart attack, asthma, heart failure, or other severe allergic reaction. You should see a doctor promptly for shortness of breath. Fatigue is a separate problem. Most people can cope with it if it is short-term; after 2 months, see a doctor.

SOB: See a lung specialist asap internet is not the way to fix this problem.

Now: There are many causes of fatigue associated with dyspnea (shortness of breath). You should see someone as soon as you can. Be prepared to tell your physician when the problem started, how it has affected your exercise, and associated symptoms (chest pain, pressure, funny or rapid heart beats, difficulty eating/swollowing, cough, etc). Good luck!

Today...: Shortness of breath is a potentially life-threatening symptom and always requires evaluation. If your doctor can't see you today, go to the er so that you can be diagnosed and treated. There are many disorders that can cause shortness of breath so you need to be seen today!
