Do I have a reason for living?

I thought about this today.
Do I have a reason to live
And if I dont
Should I continue on

Should I live my life
Not knowing why
Should I live my life
Without a meaning

Are people here
Just to live
Are animals here
Just to live

Some people know why they live
Some live for science
Some live for math
and some live for music

Do I live
As a burden
Why do I live
And do deserve it

Everyone tells me
Of course you do
You help everyone
And everything

But then I ask myself
If I help everyone
Then who
Who will help me

Do I live just to help others
Do I have no purpose for myself
Do I live just for others
And never for me

And if do have another purpose
Will i be able to figure it out
Or will I die
Not know if i have a reason to live
