It might be useful to try and record what it is you are afraid of. Looking back on last weeks irrational fears, it puts things in perspective for me. Bc all of whatever it was that i was all spooky about mostly didnt happen. Isolation is not healthy, really. It wears down the personality until there is little one has in common with other folk.
In terms of strategy for the issue? It depends on your beliefs alot. If you are rational objectivist, then charms will not avail you. But I would likely let you call me from somewhere, most people would on here. Thats super helpful, bc its almost what you need. And what you need, is support, like friends to figuratively hold your hand. Shopping especially is best done in teams.
I feel very safe using telegram. I give out the telegram number to basically anyone. You might ask some of the IT gurus here, there are a few, but it seems safe enough to me. Its a chat/texting app. With a voice chat feature.
That helps alot with the wobbly walls and sheer panic issues in public. Like a lifeline. Just some company on errands is likely a good idea anyways. For safety. I get the impression that many people on here are very isolated socially, maybe you are too. I certainly am.
In private, its another bag. Thats on you. Its training mostly, and learning to be well. And what it is in your diet thats not a good choice, if thats an issue. Such as caffiene, alchohol tobacco high fructose corn syrup, there is a long list. How much can you exercise without getting hurt? Can you get a decent bicycle and use it where you are at? Bikes are very soothing to many. Are you doing any art?
Meditation, hydration, exercise. Self hypnosis aka affirmations, there are alot of tools you can learn.
One thing to remember is you are not broken. And you are likely wrong about something like "everyone hates me" kind of thinking. Most people dont even notice you as much as you think. You are also not alone. Best wishes
