TW: talking about my anxious thoughts, just warning in case it’s triggering to anyone 

I’ve always been an anxious person, but recently since last fall I’ve become way way way more anxious. Things I used to be able to do with confidence have me extremely worried, like the thought of emailing a teacher has me frozen at my computer right now, when in the past I would hardly even think about it. I am constantly looking things up to make sure I’m doing things right even though I know I am and I feel the need to redo things over and over again because I’m afraid I didn’t do it right like locking the door. I have to verbally say to myself “I locked the door, I just checked and it is 100% locked” it’s driving me crazy but I’m afraid that I’m just using these feelings as an excuse and that it’s irritating people. I know it’s not logical, but I just can’t help but feeling worried. I feel like I’m at the point where this is affecting my life, but I don’t know how to go about getting help. Should I reach out to a physiatrist or therapist? I’ve never been diagnosed with anything so I just don’t want to be overdramatic.
