I guess accepting herself instead of being in denial of her situation was the key to overcoming her problems. Those last few panels got me a bit emotional (and I was totally expecting she would retort with something dumb or lewd to Yoshida-san).
Even if she starts to make friends and have a lot of worthwhile connections, I also think she should grow comfortable with doing things by herself. One of the best things I learned about growing into an adult is that doing some things in by yourself can be fun.
The key point here is to balance maintaining relationships with others and cultivating yourself as an individual on your own.
