What's this life for?

Someone I knew once told me
there is more to life then this
life should be filled with joy
and so much more out there

but here I ponder with thoughts
what is this life truly for  
I feel so alone sometimes
words can't seem to express

I often wonder at some point
does life get better somedays
will I ever be at peace  with my mind
where I'm free of negativity and pain

It's not that I don't appreciate things
for the most part I love being me
I just haven't been me lately
that just just scares me altogether

 I haven't always felt this way
all of this misery and pain
please make it go away
bring back the sunshine
