It sounds as though you saw a light at the end of your tunnel. A glimpse of security and happiness. That is a terrific piece of reality to hold onto!

While the guy that you met may or may not be ready for more is not a major issue. I'd encourage you to hold onto that bit of hope with all of your might! You aren't doomed to live a life completely alone. No ~ you are ready to come out of the dark and take some chances in this world. That is a wonderful big step for you to take. Just keep moving forward. Continue to take steps in getting to know others who sometimes struggle emotionally; and get to know those with similar interests and develop a hobby or two. Those things make the world feel a lot less miserable to you as time passes. Relationships will be built. Just keep holding onto that newly found hope.
