I am very anxious once again before school arrives and its so uncontrollable

This seems subconscious in that it is occuring at the same time of the year without logical cause. Now I am always worrying about the number 13 even though I don't even believe its unlucky for me. Now I am having panic attacks everyday when I create these worries and they build up to an uncontrollable degree. It is everywhere now and I sometimes feel I cannot take it. Should I take anxiety medication for this? I don't really know what to do...I worry about everything there is to worry about and my only means of salvage is the belief that I can somehow wait it out. But I'm not really sure I can...
