Is increased anxiety when starting lexapro normal? I need some encouragement

I’m a female mid twenties and started 5mg five days ago. The nausea I had at first (my other post describes it) is still there but getting better, but my anxiety has gotten worse. It’s super discouraging because i got on the medicine for my anxiety and even taking medicine is a big deal to me :(

I’ve been noticeably just anxious, sometimes on the verge of a panic attack (dizzy, can’t catch my breath, shaky etc) and been clenching my jaw. Does it get better? I’m going to of course tell my doctor but I feel alone in having this make worse the problem it’s supposed to help
