<human>: Can you condense the text into a few key points?

Excuse the lack of commas (my comma button refuses to work consistently) and grammar issues (I'm a little frantic right now)

I'm not sure if this is the right place to post this but my girlfriend of 6.5 months has anxiety and OCD. She's the sweetest person I've ever met but sometimes she gets overwhelmed by life. She used to be able to manage it reasonably well but recently she's been seeing a therapist and psychiatrist and they seemed to help at first but she's been having tougher times lately (ie trouble with her parents who aren't very supportive, stress with school, and stress from her sport). Whenever she gets overwhelmed she just shuts down and cries for hours and shuts me and everyone else out. After she calms down (usually the next day) she is back to her usual happy go lucky self and she apologies for how she acted. She's pleaded with me to not tell anyone about this for fear that she would be judged. She also doesn't want to "be a burden on anyone." 

I had hoped that she'd be feeling somewhat better (though I know this isn't a quick process) after a few months of therapy and medicine but she seems to be getting worse. She's been crying nearly every night now and her parents don't seem to want to help (they get frustrated when she cries) and her therapist seems to not be much either. I told my mom against my girlfriend's wishes and my mom says it's not uncommon for this to happen to girls this age but I just want some way to make her feel better. I don't know what to do especially since she refuses to talk to anyone about it.

Any help is appreciated.
