Me male 27 her female 33 broke up and I want her back please help?

Me and my girlfriend just broke up a clean break no arguing or blocking or anything. We both live in North Carolina and she is currently in California helping her sick 6 year old son she is donating her stem cells and a kidney to basically save her son’s life. She has been struggling very badly out there and is very depressed etc. she said it isn’t fair for me to deal with this and her therapist agrees and she broke up with me and said when she gets back in 4 months we can talk and see what happens. Is there a chance she comes back to me? Could she really just be mentally screwed right now and can’t handle a relationship at the moment? Please help! I want her back and I believe she loves me she just is struggling with everything at the moment and her son comes first I can’t go on without her we were engaged guess that’s off now I just don’t know we broke up I believe cause I kept asking for reassurance in the relationship cause she’s been very off and she’s been flip flopping a lot

And no there isn’t anyone else in the picture
