Possible Mononucleosis?

So back in August and September I have felt like crap. It started in August where I felt weird like my stomach was bloated, loss of appetite, general feeling of malaise, whoozy feelings, chills etc. I didn't have a sore throat but I was exhausted and tired most of the time. In September the first lymph node was swollen and that was the posterial cervical lymph node at the lower back of my neck. It went away after 5 days and I felt like I was getting sicker. It was around the third week of September where I had a high fever followed by a sore throat for a week and the classical lymph nodes were swollen.

Magically the malaise, and jittery feeling disappeared after I got sick. I was left with general fatigue, depression and general lack of motivation. That lasted for a long time. I didn't test for Mono but I did a blood test CBC in January pretty much a long time ago after I was sick and nothing showed up.

Do my symptoms sound like Mono or not?

Your doctor can check for mono via a lab test. Lab results will indicate if you have ever had it or if it is active.
