I just came out to my wife. I'm not really sure where to go from here.

I'm 30 years old, and have been with my wife for 6 years. She's handling it extremely well, but unfortunately, I'm not. I feel completely lost and sort of numb. I'm not sure how I'll meet people, or anything about the culture really. I've been lying to myself for nearly 20 years, and I feel like it might be too late for a fresh start. I'm sorry if this is poorly written, I'm an absolute wreck right now.
