Both of these are free and hopefully they will be of some help. There is a book that I know of called "feeling good" the new mood therapy by Dr. Burns. It helped me a lot. I read it years ago. I am sure that if you googled books on jealousy, you would find more that you might want to read.
If you decide that you want to tell your mom, just do it when it is just you and her. And be direct and honest. Tell her that you feel that you have a jealousy problem and it is interfering in your life and that you want to get help with it. Write things down that you would like to say to her and stick with it. If she gets upset or angry and you can't handle it, just walk away and go outside or to your room or something. Don't argue with her. And then appoach her at another time and go over why she reacted the way that she did. Hopefully she will understand and the two of you can talk about it. Maybe there is insurance on you. Do you still live at home? I can't remember right now.
Anyway, I hope that this helped.
Keep your chin up. This will work out. Check out those sites.
