see your doctor hun, he or she will help you the best, i suffer from panic disorder and was put on medication, it helps alot.

Deep breathing when you feel anxiety coming on. Walk away from the little thing that is bothering you (even mentallly) and count to ten.
Also take time out to think about things that are important to you and make you happy and when you feel yourself starting to panic about the little things, take a deep breath count to ten and concentrate on what is important to you.
You are on the way to making things better by admitting what you do. If it doesn't get better then would suggest you see a doctor.

taking deep breaths usually works for me.

i would definitely say see your doctor - this is actually fairly common so they wont be surprised or anything, and they can give you better advice than we can.
other than that, its just little things that will help. make sure you always have time to yourself - being around people 24/7 can be really stressful.
going for walks, reading, watching tv…find something that relaxes you,because that can help.
talk to someone - either your doctor or a friend or a sibling or something - often just chatting through how you feel can really help.
hope this helps a lil bit

I found when I used to worry about quite important things,putting them aside did the trick, eg. taking an idea out of thin air, and imagine it in your hand, then tossing it into thin air, then imagine a belief in a pizza/pie cutter where nothing really matters, and you know it's there.
