Flatlining?

So I am a 37 year old virgin, and I have achieved my longest no PMO streak, over 30 days, which is huge for me. I honestly don't have the need to watch porn anymore, but I feel like s**t. I feel depressed and my libido is super low. I met this girl the other day, and I was wondering if it's a good idea to date her. I feel so insecure and emasculated. Has anyone experienced this? How long will this last? Any advice will be greatly appreciated.
