l keep sneezing and sniffing everytime l go outside. My eyes sometimes get watery. Last year, in the falltime, l had allergies too, but l just thought l was sick. l never had any allergies before that so why do l have it now?

Most likely u have allergy rhinitis, it could be caused by stress, that dips u immune system, it could also because u were not exposed to the right allergens that could trigger such an attack. It could also be caused by change in the environment & weather. It is treatable & it is not much a problem, it will not completely be away from u but u can manage it with right medicines.

You would probably need nasal spray, & saline solutions. Worse it could lead to acquired asthma. You can have a skin test to know what allergens triggers. You could also visit ENT Doctor, perhaps u have a problem with ur nasal turbinage & for prescriptions.
