I’m 15 years old,I live in Dublin,Ireland,and I’m CONSTANTLY catching colds.I know that colds are nowhere near as bad as any type of flu,and I’m lucky that colds are all i usually get,but if i get them so often,then will my immune system be able to fight off swine flu if i get it?

For the past 3 days i’ve been feeling extremely tired and worn out,even though i have been sleeping well.this might be due to the fact ive been sitting around the house for a few days and that would probably make anyone lethargic.i’ve also been getting very bad headaches,but this could be because the air is very heavy lately.I’ve lost my appetite today,and been feeling sick on and off,this might be because i am a worrier and have been worrying that i could be getting swine flu.I’ve been sneezing alot,but it feels sort of like hayfever,however i might be mistaken.
Does it sound like I might be getting it?Or am I just getting paranoid?
the reason which im worrying about getting it soo much is because i’ve heard alot of people have died from it.that REALLY scares me.If I were to get it,what are the chances that there’ll be complications?
Ultimatly I just want to be told that if i get it,i’ll be fine,but i just keep worrying,and i need to know the truth.dont be soft on me
