The past is behind you, but let's learn from it, so you can keep moving forward.
Did it make you feel happier to stay home, or less happy?
There is no right or wrong answer here. For some people, the stress and anxiety of going out would have made them much happier to stay home. Others would be sad about "missing out".
Once you wrap your head around what makes YOU tick, you'll be able to figure out how to BE happier.
For me, going out to eat is about the conversation and fellowship, not about what is going into peoples' mouths. For others it IS all about the food.
We are all different, and sometimes we don't know what will make us happy or uncomfortable until we are in that situation. So.. like I said. Use this as a learning experience to help you learn how to make you happy
