My mum has anxiety, to be specific she has OCD tendencies such as checking the door is locked mutiple times.
I have to some extent had mild anxiety though mine was more so due to the fact that I had isolated myself at the time and wasn't getting out and had no goals. I didn't lose it until I developed an ED though I am one of the lucky ones to now be healthy mentally and physically, the things I worry about now are normal.
I don't think anxiety can leave you permenatly, though I do believe it can get to the point where it doesn't affect your life. You may have a bad thought, though you are able to be at ease knowing it will not happen. Your anxiety will simply be a passing thought.
Something I found intresting was that your profile picture speaks volumes about you, as well as the way you have worded this,
it makes me believe you give everything a lot of thought. That can be good though it can also put you in a bad position.
I think it may help if you try to do something that will make you feel better about yourself. Go to the gym, learn a new language etc...
I hope you find something that works for you
