<human>: I've been regularly chatting and have developed a friendship with someone online over the past 6 or 7 months. We had been exchanging several messages a day for months until she abruptly stopped a few weeks ago to deal with some personal issues. That kind of sucked for me because I enjoyed chatting but I understand her need for some space to address some things that are outside my knowledge of her life. We've exchanged a few messages since then, me just being concerned and wondering how she's doing, but this whole thing has made me realize I have feelings beyond friendship for her. I've found myself thinking about her way too much and it's making me sick. I'm nauseous with anxiety about it. With concern for both her and myself, I don't have any relationship experience and don't know how to process these emotions. And I can't address it with her because I most certainly do not want to pile this on to whatever it is she's already going through.

The fact that she lives in another country from me is the worst part. I know that plenty of people have had successful long-distance relationships but even making the BIG assumption that she has similar feelings for me I really can't see it working at all given our particular circumstances.

I just don't know how to deal with these feelings and it's fucking me up a bit. I've dealt with a lot of anxiety in my life but now it's attached to feelings for someone I've never met or even spoken to and very likely have no future with. I know there's always a chance, but realistically it's slim. Is this a mess of emotion that I just have to put up with until it presumably fades over time? I really hate this current situation.

Summarize the given text in a few sentences.
<bot>: I have feelings for someone with whom there is very likely no future and I have no experience dealing with emotions in a romantic sense. It's messing me up.
