As she gets older, Diana has started to loosen up a little bit. At first, being in college and the first few years of grad school were extremely overwhelming and she pretty much shut herself off from socializing; rather, she focused on making the grades to ensure she'd be successful. Now that she's moved on to her dissertation, she has started to spend a little more time outside of the lab, though she's still not sure she's got the 'being social' thing down. Despite that, she tries to have a kind word for everyone, and finds it very hard not to try to make a good situation out of a bad one; the only problem is she's not very good at conveying herself sometimes, so it often ends with her saying something stupid. Her excuse is that she's not a "word person". This "not being a word person" thing also translates to her overusage of the word "like" in everyday speech, which makes her come across as kind of an airhead at first. Once she opens up a little bit and the conversation gets deeper, though, she tends to get better at conveying her thoughts.
Overall, Diana doesn't like to ruffle feathers. She gets very overemotional in situations she feels out of control, and is well-known to be a crier. Confrontations intimidate her, and she'd rather sit back and let anyone else take the lead. She doesn't consider that shyness so much as she just...doesn't want to do it. She'd call it more apathy than anything else, but it's really because she is that shy, and constantly afraid of messing up. She's worked too hard to make herself play the part of the put-together twenty-something student that she doesn't want to chance ruining that. Sure, that may have contributed to the fact that she's lacking in social skills, but she figures she'll have time for all that later when she graduates and gets a real career.
Diana also has some serious self-esteem issues, and she's the first to admit it - at least through a thinly-veiled joke. She doesn't think she's much good at anything other than science (and even her PhD work is starting to make her question that), and is constantly comparing herself to her friends and family. She tries to just pass it all off with self-deprecating humor ("But I'm boring" is a favorite in her collection), but it bothers her a lot more than she's ever willing to admit. She tries to just smile through it though, because it isn't like she has anything to fall back onto, and she already cries enough as it is at stupid things. A breakdown because she doesn't think she's good enough is the last thing she needs at this point in her life. She's recently started making time in her week to see a therapist, and she thinks that's starting to help her as well.
Having started to recently branch out socially, Diana is terrified that all this interaction will cause her to delay her progress in her PhD program and she will either take far too long to do it or not be able to defend her dissertation when the time comes though. Still, despite these worries, she has a social circle which is dead-set on making her get out more, and while simultaneously being terrified, she's found she's actually enjoying herself, so it's a plus.
Formally diagnosed with generalized anxiety disorder in November of 2015. She attends therapy fairly regularly but does not take her medication as she should, since it makes her feel like her body's rebelled against her. She can't help but admit she does feel better on it, though.
Her smoking is an ongoing battle; She quit for nearly a year, then started up again, quit, and has been smoking intermittently through her dissertation defense. She'll try to quit for real where she doesn't go back...someday.
