Welcome ekruks and I am sorry to hear about your situation. It is going to take you time to feel better but you will feel better, so don't give up! First, make your plan of how to get a better job than being a window washer (i.e., get a better education), make "Worldly" friends, and, if you are living with your JW parents, get a place of your own. Keep posting on JWN, ask for help from other exJWs, read other threads to help find your answers, visit other websites (i.e., www.jwfacts.com, www.watchtowerdocuments.com, etc.), and read books. If you want to learn how to communicate with you JW family when they are in cult mode, you should read Steve Hassan's books (e.g., "Combatting Cult Mind Control' and "Releasing the Bonds"), visit his website (www.freedomofmind.com), and watch his videos on youtube.com. I know that some libraries have "Combatting Cult Mind Control" because I checked it out from a local library. Good-Luck!
By the way making new friends is easier than you think, just be careful and choose your friends wisely. Think about what you love to do (i.e., bike, read books, dance, etc.) and that other people like and search for ways to meet those new friends. Always smile at other people, ask them simple questions about what they are doing, answer questions that they ask you and ask them more questions about them - let them talk and listen to them. By asking people questions, you show that you are interested in them and you are also able to control the conversation. Checkout www.meetup.com to meet people to go on hikes with etc., and exjw.meetup.com to meet other exJWs.
Peace be with you and everyone, who you love,
