What does anxiety feel like ?

When I’m in a situation that makes me feels anxious , it could be as simple as driving, talking to people , big crowds , or going out to look for a job ... my body just feels weak as if I had low or high blood pressure and there’s also confusion . I feel like I’m not being the best I can be and it’s really hard to do everyday things when my body feels so off . I feel like it’s been getting worse bc I even almost fainted once bc I was so overwhelmed with noise people and bright lights
