Hi, I know this might sound cliché to you, but chasing love is rarely worth it. If you already realize you are unhappy, try to work on yourself bit by bit so that you are content on your own.
Pick up a hobby you´ve always wanted to, try sharing your interests with other people, no matter if online or not, work out or focus on improving your social skills or mental health, just try to make your life a bit fuller than it was yesterday. If you persevere and learn to love yourself, the love you seek now is going to come on its own eventually.
It´s rough out there, but know that I´m rooting for you :)
