My insecurity

Whenever i imagine
myself with you
i know this feeling
is happy and sure
yet at the same time
i feel so insecure
as i sit here
writing away
i try to explain
how i feel
i think of the times
when we were together
and you would come
sit by my side
just to be with me
and we would sit there
talking for hours
saying anything
or nothing at all
these moments
still linger in my head
but i don't want
to lament over the past
i want a future
i want to move on
but the truth is
i can't let you go
