sometimes wish that I could have a faith.....a social and moral roadmap some sense in it all,especially our own short lifespan

You don't need a faith for that. If you want to see sense in it all, a faith will simply block your view (you might still be happy, however). There are millions both with and without faith who have superb moral and social roadmaps, as well as millions in both camps who don't. A faith is a crutch that you can easily do without. Healthy minds don't need crutches any more than healthy bodies do.
