I'd bet that you will find a lot of warmth and love for yourself and your son with your mom, dad and your two brothers. They may be a source of strength and comfort for you.
Please don't tell them the details of your life with your wife. Just a few "I realized that I neglected you all" and allowing them to become important in your life may help you with your growth quite a bit. First step with reconnecting with them is very firmly yours. I hope you grab the opportunity with both hands.
