Hello there, 

My (22M) gf (22F) has been in a bit of difficult situation for the past 3 or 4 years, she is really steuggling with college because she just cant get herself to sit down and study, because the concept of sitting down to read only to be distracted by some other thing and not studying gives her massive anxiety.

This has affected her grades and has sinked her more in her pit than before. She doesnt have a support group as she almost has no friends and she feels like she cant really talk to her family about how she is feeling. That leaves only me in her life to help her get through this, basically.

From time to time she breaks down crying, saying she feels alone in the situation, that she doesnt feel supported by me. Now, I'm not really good at emotional support, never have been, but I have been trying to inform myself and study the best way to deal with this kind of situation: words of encouragement, saying that I'm here for her if she need me, not trying to offer practical solutions/trying to actually listen to what she is saying, etc. 

When I dont "seem to get the point" or I don't say the right words, she gets frustrated, saying things like "Why do I even bother with you?" or "What's the point of talking to you? It's not gonna help anyways". Although I try not to take it personal and I guess it is the pain talking, its really getting to me, I feel inadequate and insuficient. 

I really want to talk to her about this, as it's really affecting my personal mental health, but I dont want to burden her with yet another problem but I don't want to be a punching bag either. 

How do I communicate that she is hurting me without causing her more stress or pain?
