I can relate because I, too, have this problem every now and then. Yet, I noticed, indeed, that if you establish a prayer rule and push or force yourself to keep it, at least to try to keep it - it then becomes much better. About a year ago, at this time I had such a turmoil in my soul that I stopped praying altogether. This year, it did not happen.
My personal prayer rule is this: full morning prayer according to the prayer book (all the canonical prayers like Heavenly King, Trisagion, Our Father and others, including prayers to the Guardian Angel and the Theotokos, and the supplications for the Church, for my spiritual Father, for our civil authorities, for the travelers, for those whom I misguided, for the heretics etc.); one very short prayer in front of the little icon of the Theotokos when I am starting my day at work; and one rather short prayer in the evening before going to bed (Heavenly King+Trisagion+Our Father, and mental rememberance of my family members). That's usually all. During lengthy calendar fasts, I also say the prayer of St. Ephraim the Syrian with prostrations in the morning and (not always) in the evening.
I know that this prayer rule is very brief and lax, but for now, I believe, it's realistic for me to try to keep at least this short and lax rule.
