It is a little hard to give advice with the vagueness but I'll try. IMO the solution lies in your job. If you can find a way to climb the ladder so you can make more money or give yourself more free time, you'll find yourself happier. If it's possible, maybe try and find a new career path if your job happens to be a dead-end one. But once you have more time for yourself, you can focus on hobbies, pursuing relationships whether they be friends or romantic ones, and self-improvement or relaxation.
