PS or HPS Liz Cartwright? That doesn't ring a bell.
Generally, Ouija Boards and Pendula (pendulums) are crappy and can be interfered with easily, both by enemy entities and also ourselves, strangely. Your best bet is to open your Third Eye and other Astral Senses with the meditations provided.
You should do the following a lot - engulf yourself in brilliant white-gold light of the Sun, saturate yourself in it multiple times per day, every day. If you have 2 minutes of privacy, use a mantra in a positive manner and in the present tense. While visualising it and forming the mantra, picture the goal, as well. Visualise yourself free and away from the crap influences, and having PLENTY of free time to yourself. If you can't vibrate words, just use the visualisation and the mantra - you don't have to shout. Just speak it.
If you don't have 2 minutes free, then do it quietly while you're in the bath/shower, or on the toilet... I hope you have more than 2 minutes' worth of free time away from people then! Throughout the day, you can visualise the brilliant white-gold light of the sun radiating or pulsating out from your Aura (or whatever works the best for you) pushing people away from you.
Using white light/colour too much can cause you to be alone or lonely sooner or later, because it is reflective. It's also helpful in deflecting/reflecting away illnesses and other bad energies. You can use white/white-gold light in your Soul to clean it, which you should do a lot of every day, multiple times per day, as well. In your Soul, it shouldn't push people away, but in your Aura it should push people away. White light/colour is an all-around light/colour, but it is still reflective, so later you should learn to use other colors of light for things (but you can still use white/white-gold to reflect things away from you and clean yourself).
You should also use white-gold brilliant Sunlight, like a miniature Sun, on each of your Chakras, visualising them being cleaned, one at a time if you can't see all of them at once, and do this every day. Also close your Chakras - picture doors or windows or shutters on each of your Chakras, closing them, every day. You would have to repeat this several times or more throughout the day, say every couple of hours or so.
Don't put limits and expectations on any of your workings; just do these workings I've mentioned every single day and not just for 40 days but every day, and don't stop, never missing or skipping a day. If you are open and sensitive enough, you might notice differences if you missed or skipped a day, and sooner or later you should notice yourself having more free and alone time.
Your affirmation must include something similar to "in a happy; positive; healthy; safe; secure way for me", whichever ones are necessary. Vibrating Runes and Sanskrit words are to be done in the 10s of numbers, either a multiple of the number of the Rune, or 108 or 111 times. Workings are for 40 days without missing nor skipping any days, preferably 24 hours apart, and can be repeated for another 40 days - 80 or 120 days, if necessary; however, these students I've mentioned here should be fine every day without ceasing. They should never be started during a Void Course if the Moon.
You can use the seed mantra for the Sun Surya (SSS-UUU-RRR-YAAH)or Suryae (SSS-UUU-RRR-YAAAHH-YYAAYY), and 111 is the number of the Sun. When vibrating Runes & Sanskrit words, you can start low (more than 20) and then build up to 108/111 over several days or a few weeks, but never reduce down from a number/multiple to a lower number/multiple. As for the affirmations, you don't have to say it 10s of times - 3 is the number of creation/destruction; 6 is of hard work and labour; 8 is eternity; 9 is permanence for ending things.
