Lack of confidence about relationship.?

I have a distant relationship that is tiring me and due to the fact that we both have different jobs in diffeent places it started making feel wondering about the future.
We haven't seen each other for two months but we talk on the phone every single day and everything is fine and we'll meet next weekend so I guess we'll talk about it. Her job contract expired though,
but for her, moving to the place that I am at the moment is difficult 'cause there are no jobs here. We're both looking for jobs in other places but who knows how much time this will need?
One day,? one week,? one year??
The thing is that I don't feel very confident and if there are ten reasons that I'm feeling reluctant to break up with her, reason No. 10 is the fact that I don't feel confident that I will meet someone else.
I know that I am underestimating myself this way but I can't help it at the moment. Why am I feeling like this?? What can I do to make this bad vibe go away? I'm feeling that
I'm not enjoying myself and I'm having brainstorming with myself all the time.
I talked to a specialist and said that the best is to w8 for this meeting. It might end up perfectly or very bad...

What do you think? What should I do ?
