<human>: Can you give me a shortened version of the text?

Hi, I have been in a relationship with my girlfriend for the last 23 months and she is the first serious gf i have had. However, over the last 5/6 months a lot has changed as we have both moved to different universities making contact less frequent. Upon arrival to university I didn't feel as phased by the long distance as my gf, it was much more of an emotional burden for her than it was for me. 

Furthermore, over the last 3/4 months the relationship has become increasingly difficult for me to cope with given the distance and emotional strain it puts onto me. For example, making sure to stay in touch and intimate etc. This strain it has placed on me i feel has exacerbated some negative traits in my personality such as general anxiety and depressive episodes. This has led me to the conclusion to break up with her. 

However, I fear the repercussions of my decision to  break up with my [18/f] as she loves me very much and is  immersed within the relationship. This leads me to think that such a break up will harm her well being and ultimately jeopardize her time at university.We have talked about breaking up once before and it was my GF who brought it up saying that the thought also lingers in her head as well however, shortly after mentioning this she phoned up professing her love for me. 

So relationship guru's of reddit i would appreciate some advice on how and when to do the deed. This thought has been prominent for a while and i have been trying to work out a time in which i can break up as there are multiple events going on in her life which i don't want to ruin by breaking up with her.
<bot>: Title pretty much sums it up want to break up with gf however i am worried about the emotional burden it will place on her.
