Physical Blockages and Reaching the Astral

I was wondering if anyone has had experiences with physical blockages in regard to the esoteric, specifically in regard to reaching astral realms. For example, I have some health issues that are more or less permanent now, and I can no longer breathe properly as I did before. I used to meditate very deeply when I was younger, even before I began this journey, but now these blockages seriously prevent me from getting very far at all in that regard. I do still try to meditate but it is a real problem. I have tried many things, but this is not something that any spiritual practice can rid, nor can it be eliminated in this lifetime sadly.

But I feel that in order to get any real work done, I need to reach the astral.
