I'm just wondering how long it took for those who have had it to recover?

Its been 13 days, i thought i was getting better but seems to have flared up again (stuffed up, swollen gland and very very tired)

My house has been severely neglected, i've had to try keep myself away from both the kids so they don't get sick but so hard to do when they are both very demanding. I have my BFF's birthday bbq this weekend i'd hate to be sick then and possibly have to miss it
