Question for people with anxiety problems

I really didn’t think I had many issues, but my fiancé told me I need to get checked out for anxiety or start seeing a therapist. Since he said that and I’ve been thinking I do have a lot of nervous tendencies. Sometimes I worry so much about future events I can’t sleep at night. I get especially worked up at work, it’s hard for me to even talk to people/ coworkers sometimes. Other times I can feel my heart beating though my ears when I’m doing something that makes me nervous, (like going in to work or school, or giving a presentation) A lot of it I noticed is social anxiety, I’m not weird and I do know how to talk to people but it takes a lot out of me sometimes when I get so worked up. Is this just a common thing that people go through? Or do I have a problem?

I’m going through a lot right now, my fiancé has a personality disorder and fluctuates a lot and it stresses me out a lot, between school and trying to be the best I can at work, dealing with a family who isn’t okay with my life or my fiancé, its-just been hard.
