OP, it's not at all uncommon to be scared or even have a bit of a phobic fear of this. But your brief post doesn't give us much to go on.
Is it the pain? The idea of actually giving birth? Are you afraid for yourself or your baby or your partner? Have your fears always been there, do they stem from the experiences of someone close to you?
It's a big deal, all of it. Don't let anyone diminish how you feel or tell you you're being silly. But equally, don't assume that if you're scared, you have to opt for an elective c-section. There are things you can do to mitigate your fears, whatever they are. Assuming you're not going to be in labour next week, I'd advise you to talk to a proper hypnobirthing practitioner and get cracking on some techniques to make you feel more in control of your body, your breathing and your fears. There are other therapies out there if that doesn't feel right for you. Talk to your midwife - is she sympathetic? If you can afford it, you could look into employing a doula who will be able to spend more time with you, talking this through and she'll also advocate for you during birth, allowing you and your partner to relax more and know that your wishes are being supported.
Are there any local NCT or other support groups where you are? Volunteers can talk to you and try and allay your fears.
There's not much point in putting this sort of question to a social media forum though - every one of us is different and has had a different experience. An elective c-section might be heavenly or might not work out as well as hoped. A 'natural' birth with or without pain relief might go any direction. Remember though that YOU have agency here - it's your body and you get to decide how to do this, within medical reason. I hope you find a way forward through, and past, your fears.
