> I found it impossibly hard to keep meditating on my own
Couple things to keep in mind:
1. Daily practice in some form is the real key. Just get up and do it.
2. There will be ups and downs, high and lows in meditation.
3. Vipassana is a pretty austere form of meditation. You are directly confronting the mind with little outside aid or warmup. Other forms of meditation leverage breathing techniques, concentration techniques and other practices that gradually bring the mind into submission, making the no-thought part somewhat more easy to achieve. Search around or shoot me an email if you want to know some other approaches.
