Anxiety is still a major problem that I'm having, but I'm working on it.
I find aromatherapy helps a lot.
I have a few bottles of essential oils that I use. I think the smell of lavender is very relaxing. Rose really helps if I'm feeling a bit angry. And I have a mixed bottle "for anxiety" that contains lavender, bergamot, ylang ylang and lime.
Every so often, it's nice to find a quiet room, get comfortable and dabble a small amount oil onto my wrists and temples, and just close my eyes.
Sometimes, I dabble some oil onto my wrists when I'm going out. So, if I start getting a bit anxious or panicky when I'm out, I can give my wrists a quick whiff, and the smell brings me back to that quiet room.
It's not a cure for anxiety, but I think it does help. At the very least, the oils have a pleasant smell.
