Why is my MacBook Pro mid 2012 so slow

I have had this MacBook Pro for a few months and recently it has been acting really slow

I have already wiped the hard drive, repaired the permissions and even researched how to make it faster and tried all

The different ways but my Mac is still slow.

This is my first Mac and I am very disappointed after a few months my new $1000 laptop breaks down

It is unbearable to use,.
