<human>: Can you give me the gist of the text in a nutshell?

I've been dating this girl I met online since December, together since February, so about 6 months.  We live about 45 minutes to an hour away from eachother and both work full time, so we don't see eachother often except for on the weekends with scattered weekdays as well.  

 

She just started a new job this week, and her schedule will be different with working occasional weekend nights.  She is also starting a Get Fit competition at her gym with a personal trainer for the next 3 months, where she thinks she will be working out around 6 days a week.  She is overweight, but extremely motivated and excited to kick butt and reap the benefits physically.  I am excited for her as well, as she and I mesh great personality wise, so this is only icing on the cake.  I made it very clear I support her and am happy for her, and willing to help in any way I can.

 

However, I am somewhat scared of the uncertain future and the likely possibility of seeing each other less now, and I thought we werent seeing each other enough as it is already.  I've kind of had these thoughts pop up in my head over the last few months, that maybe my needs arent being met I think, but it could also be the symptom of being fresh out of a 5 year relationship (with someone who wants another chance, by the way).  

 

I just don't know what to think or do.  Do I stick it out and see how things go?  I live alone in my apartment now and have been since the ex moved out in October, so I have been pretty lonely as it is already and now I fear I wont see my gf nearly as much anymore for the next few months.  I also fear she will lose motivation and not go to the gym as much after a while, so the nice transformation physically may not even happen.  I am kind of negative and pessimistic, I have been this way as a consequence of how things ended with my previous relationship, so it is hard for me to see the good in things.  I think i am depressed.
<bot>: GF is starting an exercise regiment for a competition at her gym.  I fear I will see her even less than I currently do, and its making me think negatively.
