Aloha Kev;
Probably the most difficult part is focusing on just doing the meditation part of SFQ, whether it is the visualization part of the active exercises or moving the energy through the small universe it all has it's challenges. (doesn't matter if you're British or not 
.
If you are getting a bunch of negative emotions when practicing maybe you could try asking them what they are trying to tell you.
Sometimes the answer is not instantaneous but it works it's way though eventually.
I do know that it is best to focus on what you want in life or the answers you seek to questions. When you have mental distractions come up you just acknowledge them and go back to focusing on what you want. Don't get pulled off of what you really want in life.
If you don't know what you want take the time out to get focused on what you want in you life.
