Read about the illness online or in books. When appropriate, talk to their doctor to understand your family member's unique experience. It's also a good idea to talk to them about it, if they're comfortable sharing. You can find resources online, in your local library, or in your local bookstore. Let them know that you're there for them and want to them to take the time to get better. In some cases, they may be managing or dealing with their symptoms throughout their entire life, with frequent relapses. Let them know that you will be there for them. Talk to their doctor and/or social worker, when appropriate. Tell your loved one that you'd like to help with their treatment plan, if they feel comfortable. You could say, "I love you and want you to feel better. If you feel comfortable, I'm happy to read over your treatment plan and help in any way I can." It will likely be necessary for you to confront issues at times. When you must address a problem, always frame it using "I" rather than "you" statements. This makes your comments about you, not them. For example, "I feel threatened when you throw things in frustration. I would feel safer if you worked with your therapist to reduce those urges." Don't say, "You always throw stuff and scare me! You need to stop!" Many patients spend their whole lives managing their illness. Even with treatment, they may still experience symptoms. Don't push them to "act normal" or take on responsibilities. This could cause conflict in the relationship, lead to a setback or worse, both. Sharing your experiences with people in a similar situation can help you cope better. Not only will they listen to you, they may also have helpful advice. You may also be able to learn more about your loved one's condition. Ask the doctor or treatment facility for a recommendation. Call local mental health centers to look for groups, or search online. For example, you may be able to join a local chapter of the National Alliance on Mental Illness (NAMI). If possible, find an open support group that you and your loved one can attend together.

You are a beautiful person just by dint of being you. Your life is a precious miracle, your individuality is special. While fashion fads, preferences for certain body shapes or parts and styling requirements come and go, one thing never changes, and that is that you matter. You can always work on attitude and appearance but never forget that your very essence is something to always be proud of. Realize that you deserve to have a healthy, happy and well educated life. You are also responsible for ensuring that this happens. Confidence is a skill that can be learned and practiced. The more you put it into practice, the more it will become second nature. If you grow up in a gregarious society, such as the United States, it's an expectation, so you'll have plenty of role models to imitate. Smiling shows that you're happy and comfortable in your own skin. Smiles suggest that you're approachable, friendly and nice to talk to. Don't just give the impression of being nice, then fail to deliver. To be seen as beautiful, it's important to exude a beautiful attitude toward everyone. That means showing other people kindness, consideration, thoughtfulness and compassion. Each of these will add up to your beautiful aura. Make the most of your natural talents by working hard to hone them. Learn as many skills as you can so that you can be self-sufficient, capable and most importantly of all, competent. You owe it to yourself to be a fully-rounded person who can do things for herself.
