Hi mochadia,
I purchased the course 5 years ago. Honestly, it has its strengths and weaknesses.
First of all, you're a new mom (congrats!) so feelings of depression, loneliness and envy could just be a post birth experience. Many new moms suffer from the so-called "baby blues". It's a matter of hormones and lack of sleep - so I'm pretty sure this issue will get back to normal soon even without feng shui. I have two children and I went through this, too. It's not unusual at all.
However, I am quite sure that the course can help with the topics you listed. One the other hand you could also check out the cost of a good feng shui practioner/master and invest the money in a classical feng shui consultation.
In Chinese tradition, feng shui represents only one third of your entire luck, another third is your behaviour and attitude and the last third is heaven luck (the family you're born into, your horoscope etc.). Feng shui can support you, but it's not all feng shui. Attitude and thinking play another important role in your life (the essential course helps you with your goals, too.)
Love,
Astrid
