How can I tackle spam that came from my own e-mail address that I did

That's called "sender forgery".
Unfortunately there's no real way to _prevent_ it. You can reduce it
somewhat by employing various sender authentication mechanisms, such as by
publishing an SPF record for your domain or by using DomainKeys/DKIM to
sign your legitimate outbound mail. However, for these to work the
recipients need to check that information, and not all recipients do this.
Implementing SPF and/or DomainKeys/DKIM for your outbound mail traffic is
offtopic for this list; google those terms along with your MTA software
name and you should be able to find useful information.
