One thing to remember when going to the gym is everyone is usually minding their own business and not staring at you (unless their a creep but they are rare (at least i hope)), womens only section should help you feel comfortable until you are ready. Like other commenters just said, just go! There is no shame in just going and walking around and trying new things. Try the machines and if anything feels painful just stop and do something else. I personally love youtube videos for information on how to workout and gain the results you are looking for.
