Can you please help me paraphrase the sentence:
It made it very hard for me to become socially adept
so that the meaning of "socially adept" is expressed in a single noun phrase or a noun? As in:
It made me a _________. (some kind of person)
One possibility is well-adjusted, which Merriam-Webster defines as "able to deal with other people in a normal or healthy way".
However, you can be well-adjusted but not truly adept, which suggests a high degree of ability. Whether well-adjusted fits will depend on what you mean by "adept".
