It seems that MyMonero.com has been hacked and a lot of XMRs are gone. Mine probably included. I want to check my wallet and send out everything as soon as possible.

I setup full node, synced blockchain but when it comes to seed recovery, it needs 25 words recovery seed or keys. I have only 13 words recovery seed from mymonero (from hopefully not hacked version) and no keys.

I cannot get keys from mymonero.com (i will never login there anymore).

How can i solve this situation?

Thank you and DO NOT LOG INTO MYMONERO.COM (never) again!
