First Time Going to Therapy and Feeling Nervous

So I've got a new therapist, and my first appointment is on Tuesday. I'm kind of nervous, because I've never had a real therapist before. My current doctor is just a prescribing psychiatrist, and she's the only doctor I've ever had for mental health. I just kind of feel like all she does is throw drugs at me to see if it does anything, and considering I'm on three antidepressants, two maintenance anxiety pills, one ADHD medication, and one medicine I take for panic attacks, I feel like I already rattle when I walk. So I found this new place that has a prescribing doctor, but you also see a therapist. it sounds kind of intense, because you're supposed to go 3 hours 3 days a week, so I think that's what has me feeling nervous. The good news is they provide transportation, which is the only reason I can go to them, since I'm mostly blind and can't drive. but between anxiety and my blindness, I'm feeling kind of anxious about going to some completely new location and being around a bunch of people that I don't know for 3 hours. I think this is going to be really good for me, but I really wish I had someone there to hold my hand this first time. Lol I'm also kind of excited and nervous because I have another doctor's appointment on Thursday, and I'm hoping they will confirm the PMDD diagnosis and maybe put me on a hormone to help that out. anyone have advice for the new therapist situation? Like I wonder if they'll think I'm weird if I take some fidget toys in my pocket or something. I'm in my 30s, so people tend to think I'm too old for fidget toys, but they still help with both the ADHD and anxiety sometimes.
