How do I get rid of constant spam from inbox?

Question

My inbox is inundated with spam/phishing emails; some that have an obvious hacker address, some that appear to be from my own email address, and others that don't have an address at all, just a name like 'IRS Government' or 'Slots Gallery' or 'Bitcoin Millions' to name a few.  I'm getting roughly 20 plus spam emails daily (been going for 6+ months) and I can't seem to do anything about it.

I can't create a rule for the emails in my name/emails with no clear address to send them straight to deleted, as the system wigs out and just says “We can’t create your rule at this time.”  I have created rules for specific words that appear in the spam that I know would never pop up in my normal emails, such as ‘casino’ or ‘steroid.’  But half the time these don’t work because the email content appears to be an image and not actual writing in the email, so the words are not picked up in the rule.  How do I stop this spam?? I like a clean email and this is driving me insane!!
