It's only recently I've thought about anxiety as a medical condition. I always thought of it as a state or mood, usually brought on by circumstances. "I am feeling anxious," "That makes me anxious," etc. And then the situation passes and so does the anxiety.
But persistent anxiety: I really don't know where it comes from or how to treat it. I don't think I have a lot, but I don't want any.
But me and depression are old enemies, and have you listened to symbols and I? Depression isn't impossible to control. It's just a bit boring and takes awhile to really see improvement. But it happens.
Do you exercise multiple times a week?
How's your diet?
Tried any meditation techniques AND kept up the practice?
Drinking enough water? (Really! That's no small thing.)
None of these help immediately, but even a week of being good to yourself starts to pay off.
And if you want to reply "I don't have time" I would say "Yes you do. Prioritize. Cut down on something to make room for self-improvement, then you'll have the mental/emotional resources you need to tackle your responsibilities with greater ease."
I know. It's a drag. You have to find the strength to even start, and then find even more to keep it up. But I can assure you that a bit of self-care on a regular basis really does help tremendously.
And it is about "controlling" depression. Not curing it forever.
But anxiety? I dunno. Hope someone can explain it's root causes and common treatments.
