Another way of framing self-sabotage is that you are doing what it takes to get what you want.
Find a quiet room. Dim the lights. Sit in an upright but not rigid position. Uncross your legs. Place your hands lightly on your knees. Close your eyes. Wait about 30 seconds for your thoughts to become quiet. Out loud or in your mind ask yourself the question “How is keeping myself single benefitting me?” Then wait for an answer. The brain is naturally a questioning and answering machine. Your subconscious will speak up here.
Peacefully ask yourself the question “What would my life be like if I didn’t need ____ (put the answer from above here) ____ ?” Then let an answer come to you in words or images or a feeling.
Now, speak to the same part of yourself that has been answering you, “I no longer need ( the answer from the first question ) in my life in order to be safe or happy.” Wait for a reply.
That could wrap up the whole session in about 5 to 10 minutes. Or depending on the “reply” you get, you may decide to continue working through things by repeating steps 2 and 3 while responding to the reply from step 3 the same way you would the answer from step 1.
Your reply will be affirmative and positive and you can consider things taken care of. Or it may indicate further work needs to be done. If so, you can continue the session until it becomes affirmative or just end the session and come back tomorrow and start again right where you left off; using the final answer you were given to continue.
When getting started waiting 30 seconds can be enough. If you need more to reach a light state of relaxation, you can visualize yourself slowly walking down a set of stairs, picturing each stair as vividly as you can, counting in your mind from 10 or 20 or even 100 if you’d like, all the way down to 1.
