Claire, ½ is not too bad a proportion. Everybody has her or his own abilities and limits. We cannot expect to live in perfect understanding with all other people, but we can improve it with each one. You can ask us and others for advice, but in the end you must solve your problems yourself. Start with your journal or diary!

If you need technical advice, please tell us more about the equipment you have available, and who else uses it. Encryption can be much easier than suggested in the above posts.
