Nacho, RoyalC130 is correct. The active meditations is the best thing you can do for your overall physical health in SFQ. You can use the other techniques to work on specific problems like cold sores.
Small Universe and Self Concentration are very good meditations, but it's hard to believe you are maintaining a positive attitude. It doesn't come across in your posts. What I sense is anger and fear, although you've stated that you've lost the ability to create emotion from thought a while ago. I understand it may feel like you don't have control, and no you can't control everything. That's one of the reasons that Faith is one of the six keys to success in SFQ. It is also important to be calling on master(s) for whom you Have Great respect. Respect for what they are, what they represent, what they can do, and for SFQ I think for how they care about you.
Please put yourself into the Weekend healing sessions. Distance is not an issue for Qi.
I won't try and explain the feelings you're going through. It may take time for energy blockages to move. For some people the clear quickly, for others it takes multiple sessions, and others still need SFQ and other modalities. Have you considered other modalities to help your SFQ work.
Now the last bit I want to share is from the Abundance for Life course. It's the Feelings Exercise. You can find enough information on the forum to understand it. It has several levels, but the basic form of the meditation is all you really need.
I was about to say what I found, but it's best to just do it and follow the instructions of not labelling the feelings and not judging them. This is close to the idea of not letting you conscious mind get in the way of your SFQ experience, but it's desire to categories and claim it understands everything.
The Feeling Exercise doesn't have you move energy, it just has you exploring what you are feeling and then appreciating the gift of the feeling (This is where labelling will get in your way). If you label or judge any feeling you will have difficulty. It's wasn't easy for me, but I was pleased when things finally happened. When I came through this experience (not successfully the first few times) I could look apon all feelings (energy) and gifts, dispite my old and sometimes negative labels.
Because of this Fear is one of my best friends. I'm still working on making anger a good friend. 
Nacho, remember to be Kind, Loving, and Forgiving of yourself and everything in your world. Try and merge with the peace and love of the universe as you start SFQ, but don't judge or label the experience or your percieved level of accomplishment. You are experiencing what you need to experience, and following SFQ will help you to completely heal. 
You Are Perfection.
