Nothing can jack up our self-confidence faster than family. For the bad dreams, I would recommend a dream catcher that has citrine incorporated into the design. Citrine is well known to help protect against nightmares. If you are a crafty person, you can create your own dream catcher using citrine chips sewn into the weaving.

As for your inner peace and self-confidence, I would recommend incorporating a mala into your spiritual practice. Malas are prayer beads, which when used with positive affirmations, can create an amazing amount of change within a person. Since you live in Stafford, you aren't too far from 13 Magickal Moons, and we have a decent selection of malas in stock with more becoming available right before Christmas.
