Why am I like this?

He finally asked me out After a year of anticipation and waiting He finally asked It should be an exciting time A time that should feel like a high that only teenage love can bring A time that should be filled with shrieks of joy and exhilaration And yet When I see his text I freeze with fear No thoughts in my mind No smile on my face It shouldn't be a terrifying time A time that shouldn't feel like a low that only your worst nightmare can bring A time that shouldn’t be filled with dread and panic Why am I petrified of the possibilities to come Why can I not experience that same euphoric feeling my friends do Why am I like this
