I'm sorry to hear you feel low. I totally understand what you say about wanting company and how seeing people holding hands makes you feel more lonely. I agree with what divine1966 says, it's important to find happiness on your own as a first step. That will radiate out and attract others towards you. I've tried on-line dating on and off for several years. My experience is that you have to invest quite a lot of time searching strategically for people who have similar characteristics to you. Then your changes of success are increased. Also you have to be develop a thick skin and not worry when people reject you. It is a filtering process, which will hopefully lead to the selection of a soul mate. I would also advise trying off-line dating. Above all, I think you have to keep your faith and keep going. In the end it you will find someone that is truly right for you
