Mental Health Support

There are mental health help lines who might be able to suggest things for your anxiety and panic issues.

There are different types of anxiety. You may well already know. But in case you didn't, I would get to the bottom of that as treatment varies with the type.

My wife has it. I know the drill pretty well but I'm not a doctor.
Keeping active helps her.
There are supplements that help. Calming herbal tea and peppermint are two she uses.
Avoid caffeine.
Get exercise.
Meditation, breathing exercises, mindfulness might help.

I gave my '60s Tele to my brother-in-law after my sister treated him poorly.
I buy broken guitars and make them into what I want.
I miss the Tele some but I've made a bunch of 'great new friends' salvaging them from the scrap heap.
Nearly all of them are technically better guitars.
But none of them sound quite like the Tele.

Some quiet classical music or laid back music you like can help calm you.

Getting a plan together to deal whatever is making you anxious helps calm you.
You ask a bunch of folks (maybe online) and note the advice that seems applicable/appeals.
You get 5+ brains working the problem brainstorming for solutions. You get a better plan.
If you can get some skeleton of a plan that makes some sense, it will help anxiety because you have some idea how you are going to get through it - not so overwhelming.

You're not licked. You came to a good place.
Hang in there. Help people help you.
