How can I make my own forum?

Yes.  Already told you.

You need a hand getting started?  Start with the database design; think what you'll need to record.  E.g.:

Date/time of posting
Email address of poster (will not necessarily be displayed)
Name of poster
Text of message (consider whether you'll want to provide a UBB code feature, or just plain text - allowing HTML is not a good plan unless you can write a REALLY good parsing sanity checker)
An approved/not approved field, if you want to moderate all messages
IP address of poster (although it may be spoofed if you do not guard against that)

How do I design this database?

Go to library, bookstore, Google, take a class, etc. and start working on it.

I have cPanel.
I will try to make a database, but I think I am out of databases!

If you have a MySQL database already, you can just create another table within that database.  You don't have to keep it separate.
