<human>: Hi! I am a 29 yo caucasian female, 5'3", ~130 lbs.

In the past 6 months, I have gotten the same type of cold about 1 time each month. 

It happens in this order: 
1. sore through
2. sneezing and a runny nose
3. sinus congestion
4. tickle in my throat
5. mucus in my throat
6. small cough that gradually turns into a big cough with mucus
7. my chronic asthma gets exacerbated and at that point I usually need to take meds to help me breath 

I have a healthy diet consisting of mostly vegetables, some fish, eggs, lentils and legumes, and fruit. I typically drink ~100+ oz. water each day. I do my best to sleep 7-9 hours each night. I wash my hands constantly. I have been under stress on and off for the past few months due to moving and starting a new job, but I have been meditating and doing some sort of of physical activity (working out, going on long walks, hiking) each day to help deal with it. On the average week, I drink alcohol 1 night/week. I take a multi-vitamin each day. I have moved through several states in the past few months, so I do not think this is related to seasonal allergies.

I got sick frequently when I was really young, but over the years my body has appeared to fight off things better. I typically get sick 2-3 times each year, but this year it has happened more frequently.

What could be causing me to get sick? Is this particular cold path related to a particular virus? Could I have a virus in my body that doesn't go away and just stays in my body until it wants to pop back up again? What else can I do to help boost my immune system? 

Thank you!!

Can you provide a brief rundown of the text in within 3 sentences?
