Are you doing a Couch to 5k ? if not, you should check out the program. It's a program designed to ease a non running person into a runner. So, if you're brand new to running, you may find this helpful. www.sparkpeople.com/resource/fitness_artic
With regards to your concerns, it's not unusual to have some anxiety when trying something you've never done before. It's like the people who are afraid to try Zumba because they think they'll do something wrong and people will stare.
Believe me, there is nothing to worry about. We all had to start somewhere. Your strength and regular endurance will increase with time and practice.
As the old cliché goes, how do I get to Carnegie Hall ? practice practice practice.
Keep doing what you're doing and you will feel more comfortable.
PS - Were you fitted for proper running shoes before you started running ? One thing I recommend to all new runners is that they should go to a reputable running or sports store to be fitted for a proper pair of shoe. Don't wear any old shoe. Wearing the wrong shoe or shoes that aren't fitted right will cause a lot of problems for your feet, ankles, knees and hip joints.
So, don't skimp on your feet. When you start getting into longer distances, your feet will need that support so that you don't end up injured.
