You need to focus on being happy by yourself before you try dating. If you jump into a relationship relying on them to provide you happiness it will put pressure on them and the relationship will fail. You need to make yourself happy first. Hang in there. 😃
I would start by joining groups that you find a interest in and start becoming part of the conversation and community. While most groups do not want you to to seek out love on their page it will connect you to people with the same interests that you have. Start new friendships that can develope off the page and see where they take you. Any good relationship start by a solid friendship. Good luck!
