Scared of taking medication

TW MENTION OF MEDICATION AND INTRUSIVE THOUGHTS ABOUT IT. Hi everyone. So basically as the title says, I’m scared of taking medication. I’ve been prescribed 10mg of fluoxetine (Prozac) and I’m just scared of taking it. Well any medication to be exact but this is the one I need to take. I’ve been on it before and it worked wonders for me even before my ocd got bad but I went off it about 3 years ago and since then it’s been pretty bad. I first was prescribed fluoxetine at 11 years old and switched around a few times since but I always came back to fluoxetine. Since then I have taken genesite testing which said fluoxetine is my perfect match. Even with all that I’m still scared. Maybe it’s because I did try it again January of 2024 but one night I was struggling to sleep on day 3 and it felt like I stopped breathing when I was half asleep half awake but that has happened since and it was like a half asleep half awake thing where I was breathing just it slowed to sleep Yk. so I stopped taking it immediately and I’ve been scared to since and since then I’ve been scared it taking all medication even tums or Tylenol. A few new reasons came along as well. Here’s the reasons with my logical side featured so you understand my thought process, What if I’m suddenly allergic? Super unlikely but still a fear. What if it’s drugged/poisoned? Super unlikely again. As far as I know it’s never happened with medication you get from a pharmacy. What if the side effects make me really bad again? This one I have no come back for tbh. What if they don’t help? That’s literally what they’re made for. They can always up my dose or change medication. What if it takes me years of struggle to find the perfect medication? Yet again no come back. What if it doesn’t help my ocd at all? ITS WHAT ITS MADE FOR. What if it makes my ears ring worse? I have ear ringing currently and had it one other time and that guy went away but this one isn’t for some odd reason but it’s only been 3 weeks and I think it’s because of the tubes swelling because of the weather. But I did read about it one time making peoples ringing worse so that scares me. So there’s my reasons. Some illogical some with some research I would know the actual facts. Thankfully I’ve gotten to a point where I can touch the medication without freaking out. Mainly because my husband got prescribed the same exact thing and he graciously allows me to hand it to him everyday so I can get comfortable with touching it. I’m just looking for some advice on how to work through this and get to where I can take my medication.
