The desire to be healthy and the things I do sometimes are oppositional too. I'm afraid to do that with meds though because my brain is already screwed up enough as it is. There was a time when I was on an SSRI medicine and I was so afraid of messing up my brain chemistry, that even though I was half hearted about the drug, I took it as prescribed routinely. I didn't want to skew whether or not it was working for me. My mind told me that if I did it haphazzardly I'd be shooting myself in the foot. What does your mind tell you about your inconsistent medicine use?
Depending on what you believe about the medicines and what benefits and conscquences they have for you... you're right, Ayesha it can be self actualizing a self destructive pattern (as you also say you do that with people). But on the other hand, sometimes we get insights from the struggles and it is a growth experience. You are aware of what you are doing... the meds and backing away from people. You might not have had this realization if you hadn't gone through this. Just remember it's not a permanent thing... it can change.
For me, the backing away from people had more to do with trust issues, and not knowing how determine safe people and safe relationships. It was being so aware of my past choices that brought me the realization that I didn't have any tools to pick or choose socially. My core belief was "Everybody's out to get something. Everybody will lie to you and hurt you." I found I needed to spend some time learning about what a safe person or relationship was... when I did that, I was better able to do the people thing without reverting into isolating behavior or pushing away.
Perhaps pushing away people who want to help you has to do with beliefs around your sense of worthiness? Do you not feel worthy of help?
Just wanted you to know I hear you, I'm reading, and I hope you are able to get some answers that will move you forward and that things will change and improve for you!!!
