Locked out of my site, by bdk437

Not sure what version I have. Always updated it… I hired someone years back to setup my site so Im not very experienced but Im in trouble now because I can not get in and Blue Host can not help.
My trouble started when I noticed Jetpack sending 2 emails everyday at almost the same time. One said your site is slow and the next 10 minutes later said Im back up. I went into my site to the Security page and found a list of errors with a ‘fix it’ next to each one. I went down the list and fixed everything. Then my problems really started. Jetpack was sending many emails a day. Next thing I know Im locked out and can’t change password. Box just shakes.
Bluehost tried to help and found one backup and installed it. Still can’t get in. I use Backup Buddy and have a few more old backups but can’t access them. My site still comes up but can not get in… I think I need to take a class on WordPress…
Can someone direct me or help me fix my issue?
