Firstly, I want to welcome you to our humble community! :)
It took a lot of courage for you to seek help for something so new to you, still. You could have refused to accept this new possibility but you faced it head on even though you weren't quite sure what you would see - and for that, I applaud you. Takes a lot of courage but most of all, it speaks well of you as a husband and as a father. I understand you are afraid of not being a good enough man to be a husband to your wife and a father to your young boys, but I believe you drew this immense amount strength from your love for them. And that speaks volumes.
I am very glad to see you are seeking out a professional and recommend it whole heartedly. I have been in counseling off and on since I was very young and am well aware of how life changing it can be. If I may offer advice, do not be afraid to be picky when choosing a therapist. A huge part of therapy relies on the connection between the person and his/her therapist. It also relies on your comfortableness with discussing hard topics and digging deep and while this is difficult, it isn't as difficult if you're speaking to someone you trust and you connect with. You are discussing things that affect your future, you are allowed to be picky.
