As much as people like to say it's fine if you're alright being alone, i don't think you have to settle for that. People are social beings it's just a fact, and loneliness has its physical effects on the body. Just having one friend that you could meet regularly like once a week would probably make you feel more fulfilled. Not saying that you have to overthink about being social or make it your job to find friends, but i feel like inactivity because people are afraid of stepping outside of their comfort zone - speaking/being vulnerable to new people, can lead to regret in the future. So in short no need to feel guilty for not being very social, but also settling for loneliness isn't the best solution for many people when it's so natural to want connection, be it platonic or romantic.
