I lost my Passphrase to my bitcoin core wallet what can i do? Please help

If you have some idea of what your password is, you can try to bruteforce it. There are some tools that you can google that allow you to brute force wallet passwords. You could also try http://www.walletrecoveryservices.com/ as they can recover your password through bruteforcing it.

Otherwise, there is absolutely nothing you can do.

This might be a stupid question, but is there any BTC in the wallet? You didn't mention this, and if the answer is no then you can simply rename wallet.dat to something else and core will create a new wallet without a password.

These are the best tools to try to recover your password: https://github.com/gurnec/btcrecover (https://github.com/gurnec/btcrecover)

Hope you recover it.

Not alot to be honest  :-\  and depending on how complex your password was it might not even be worth trying to guess it.  If you can sorta remember parts of it then yes try the brute forcing tools, but if it was a long random selection of characters then i am sorry my friend but them btc are gone.

He is right, if there is no BTC in it it might not be worth recovering it
