<human>: Give me a shortened version of the text

So I'm a pre-med major in college and I'm stressed and she knows that.

She is holding a lot of stress to the point of where it's affecting her sleep, family stuff, personal stuff, school stress etc etc.

Any time I want to talk to her about it she always wants to protect me and shield me from her laying a bunch of stress on me and talking about it.

I know that it will stress me out a bit, but it's nothing I cannot handle and she's so reluctant to talk to me about it and relieve it because she thinks I'll get too stressed out and start failing classes. 

She has good intentions, but I want to talk to her about it. We had a conversation awhile back about her stress and I'm trying my best to help her, but it's really difficult because I'm not there physically to comfort her.

I want to talk to her about it but I don't know where to begin.

I want to talk to her about it, but I don't want to probe and be too controlling.
<bot>: my ldr girlfriend of 8 months shields me from her stress instead of talking to me, and I want to be there for her. Where do I begin? I want to know that I will be there for her no matter what.
