My answer is yes.
It's not as good a meditation as if you were calm, happy and focussed.
All of the level one meditations are for your personal healing. They work on different aspects. You should use them all. I think the self-concentration will be gentler for you and help to build confidence. If you have difficulties about what to think about during the none guidance, I will say keep coming back to positive and happy images, scenes or thoughts. Perhaps a place and time when you are not bothered by your current concerns are completely emersed in the loving, caring, supporting, boundless energy of the universe.
Remember to keep heading in the positive direction. You don't have to be there all the time, just gently correcting you course with kindness towards yourself. Don't judge your performance, the universe sees no failings in you and who are you to second guess the universe.
You are perfection.

P.S. The universe didn't judge me for my mistakes... it just pointed out to me that I needed more focus... and to correct.
P.P.S. I would also add that you should be considering the other elements of SFQ and not just the meditations. Rest, nutrition, exercise, mental attitude. It is amazing how they are all part of a whole and how a the correct balance is needed to progress with the others.
You mental awareness and control, can be worked on outside of SFQ meditations. In fact, at this time it may be better to work on it at a conscious level. Always supporting it with balance and flow.
At times I've given up meditations and other things and taking the time just for extra sleep. It has help incredibly in regaining the health I needed to pursue my advancement in other areas.
At other times, just talking a regular lunch time walk has worked wonders for my mental attitude.
Using NLP like positive visualizations have also helped often both mentally and physically.
My observation is there is no single magic key. The magic is in keeping all elements in motion and balance. The magic is in the juggling, not the balls.
