Hi Pezar,
Welcome to the hobby. Don't be afraid to join in. It may sound like all hams know each other, but they don't, they're just a nice group of guys that are very friendly. Most new hams are "mic shy". The only way to get over it, is to get on the air. Don't be scared to call CQ. Just ask first if the frequency is in use. If nobody comes back, start your CQ. If you have "stepped on" someones QSO, the worse that will happen is that they will come back and say "the frequencies in use" You then just say you're sorry, ID your station and more to another spot. If someone does come back to your CQ call, you can just stick to the simplest form of a contact where you exchange callsigns, your names, QTH's and signal reports. After that if you don't want to keep talking, just say, "thanks for the contact, 73 and sign off with your station ID. Or if you want, talk about the weather, or explain how your new to ham radio and just wanted to make a contact.
The nets are another good way to get your feet wet. Try the 3905 Century Club Net. They are a bunch of nice guys that just exchange QSl cards for different awards such as worked all states. check into the net and tell them you are new. You'll get lots of calls. The exchange is just each others call sign and RST report. You don't carry on a long conversation, just a quick exchange. There is a net control and he will go down the list and tell each operator when it's his turn to make a call. The meet every night at 7.188 mhz at 23:30 UTC. which is the early net and again and 04:00 UTC, the late net. Google "3905 Net and you will find their website with lots of info. Listen in a few night sand you will get the idea of what's going on so that you will be prepared to join in.
If you are really, really shy about talking, another option is PSK31. This digital mode is a lot of fun and it's basically sending real time text messages most of which are just pre-programmed macro message that you send with a click of your mouse.. No talking per se. It will require a computer and interface to your radio, but most already have a computer and a signalink usb interface is about a $100. If your even shy about exchanging text messages, look into JT65, another digital mode, it's a very simple way to make contacts all over the world by just sending call signs and signal reports with alternating 13 character messages. Sort of a twitter for hams.
Also, if there is anyway you can find a local amateur radio club, You will find lots of guys willing to help you. Whatever route you take, I hope you join in and have fun with us.
