Just do whatever makes you happy. And if you have anyone on your life (family, friends, etc), then reach out. You don't have to pour your heart if you don't want. Just talk to them. Ask them how their day was. What did they have to eat today. Socialize. You can always start conversations here or in other communities if you feel like you want to do that instead.

You're not unhappy because you're single. Plenty of people are in relationships and are unhappy. You saw that yourself with your parents. You need to stop making a relationship seem unachievable and having it tied to your happiness and sense of self worth.
