Hi Cate, so sorry to hear you are having a bad reaction. I was going to write to you about anxiety and not ignoring it (because pushing things away tends to intensify them), but now after reading your last entries, I really want to write to you about what I have discovered about it.
There is an idea in psychology called avoidance coping, which means trying to avoid certain thoughts and feelings because you are afraid of what they might trigger. Like maybe someone overeats to avoid feelings of hunger because they are avoiding those bodily sensations that maybe get associated with an uncomfortable psychological feeling of emptiness or loneliness or other things that make the person feel anxious. So maybe food becomes like a companion, and normal hunger gets associated with something to avoid. Other examples - you don't want to think about something stressful because it triggers painful memories from the past, or you don't talk to someone about something that stresses you out to avoid their potential anger or rejection or to avoid an awkward conversation (or with me and my social anxiety, just looking awkward, period)... So you can avoid painful feelings by focusing on something else (eating, or even ruminating too much to try to think one's way out of uncomfortable emotions), or by not doing something (putting things off that you know would be helpful in the long run). These types of coping may be great for when you are in a dangerous situation or in a situation where you just can't relax and process, but in the long run, they are not good coping strategies because they lead to stress and avoiding one's true feelings.
So I think meditation or any form of relaxation exercises like deep breathing, anything where you soften your body and just sit with what you are feeling (without judging the feelings or yourself) are very healing. And the nature of even strong emotions is that once you feel them, they pass. Actually often my hardest to sit with emotions often morph into increased energy or even happiness once I feel them. This doesn't need to be some formal exercise even. It can just be sitting with a cup of tea and relaxing and feeling all the muscles in your body relax and letting whatever feelings come up come out, and just letting them express whatever it is that they need to express. Also you don't need to act on the feelings necessarily unless you see that this would be helpful and you feel like you really want to. It's more about just feeling what you are really feeling. I hope I am making sense!
