How do I put myself out there?

I came back home from abroad after losing my job a few months ago. I feel isolated because I only meet my friends and my family, but at the same time, I am very reluctant to meet new people and it's making me anxious. I feel that they have great expectations because everyone thinks I am or I should be more intelligent than others or people think I am weird because I have some mental issues: emotional inconsistency, social self-confidence oscillations (when I am not anxious I am very confident and funny, when I am anxious I am extremely shy, neurotic and dysfunctional).
