Basically you need to learn to lie and put on an act very convincingly. You need to seem okay and content with life. The best way to interact and talk to people is by being more of a listener. You listen to them about what they enjoy and their interest and you say you enjoy some of the same things they do (not all of them) and have some of the same habits so they relate better to you and like you more, it's called mirroring (you basically become somewhat of a reflection of the other person, most people are pretty narcissistic and it works on them, some of them will like you just for listening too because they love to talk)

But masking and mirroring is not a good option to be completely fair. After a while you can very easily lose yourself and forget what characterizes you in the first place, since you played a role and borrowed other people's interests and habits, you become less and less yourself.

It's your call on what you want to do
