<human>: I am recently out of a long relationship (for me.. just over a year).  I decided to break the ties because my work was enveloping my life and frankly my girlfriend did not really care, and if she did, I never heard it.  I know it is my fault, not trying to fix that.. I am trying to fix me. 

Right after I got out I started talking to a former friend, someone who I had met previously but had forgotten (long story).  Anyways, I have basically fallen for her in the matter of a month and I really dont know how to handle it.  I dont know if this is just my emotions going crazy or if it may be worth something, the main issue is that I really do not have any friends these days.  My day consists of work and home.  I need to get out there and meet people, but honestly I am not quite sure how.  Up until I started my own business, I had worked around a bunch of people, hung out with them, etc. but now I work alone so interactions with others are limited at best.  

I have a major issue that when I am alone my mind goes crazy.  I over think things, I worry, etc.  I am having a real issue controlling these issues and not sure what I can do.  It causes me to check my phone constantly.  

I feel like I am in a bit of a hole here and not sure how to climb out, yet the longer I stay in the deeper I go.  I have severe social anxiety but it only lasts a bit.  If I am out with a buddy or something I can open up quite fast, but I dont particularly have anyone to go out with unfortunately.  

I guess confidence in myself would be nice, but talking to women is way out of my norm.  I know one must be confident in themselves before being able to meet others, but I find that I draw much of my confidence and who I am from others.  Sounds odd.. but it is how I see things. 

Constantly questioning every move, yet trying to open up.  It is not the easiest. Any advice?

Can you condense the text into a few key points?
<bot>: Newly single, falling head over heels for someone new, really screwing it up, not sure if rebound feelings or if they are true.  Please advise.
