Can someone tell me how to write in bold and italics?

I am firecracker
Brought in by my parents
With basic needs and education
I was lit.
To tell you the truth
Im mostly burned out
No exquisite light whatsoever
Simply put,
The plan is to shoot high
And bright, at a pace of my own
Before the angel
Lights me out

Please carry it gently
its been crushed, torn
and fixed
Yet again,
this is one of the
many times I trust
You might drop it too
and somebody else would
mend it their way
But none will be able to
piece it in the pattern
like it was when
first broken

The white pages are smeared with ink and tears.
And I never tell a soul what's written on those pages.

It's the days when you don’t cry,
But you don’t smile either.

It’s the days when you’re quieter than usual,
And people notice.

It’s the days when you aren’t quite thinking about anything.

But if someone asked you what was wrong,
You wouldn’t know where to start.

Be like snow
     beautiful to watch
                but hard to catch
