Being in love means experiencing a whirlwind of emotions, and these emotions can be both positive and negative. When you fall in love euphoria is mixed with doubt and fear. One minute you are on cloud nine and the next you are falling into depression over some perceived slight. Being in love is not easy, and the emotions that this state causes can affect all areas of your life. You may not be able to concentrate or think about anything other than the one that you love. Over time the emotions will stabilize as the relationship grows and deepens into mature love that lasts.
