I like to share this eBook that i found today : The emotion code (also with audiobook and flowcharts downloads in the link) from dr. Bradley Nelson. It is about finding, clearing and dealing with stuck emotions (grief, anger, depression, anxiety, frustration...).

Not sure how long it stays there as a free gift. The book alone costs around 20$. Here is a link to amazon for those who like to buy or read reviews:
