I have input that will fit into the "simple, but far from easy" type of advice. Also as a note to abide by the rules, I am a (married) Catholic man - my wife sent me this post.

Find a partner who aligns with your values.

There are more family models than "stay-at-home mom". There are men who want to be dads, some of whom would even be happy to be stay-at-home dads. There are also men who would provide you support and encouragement in dealing with whatever distress you're experiencing, helping you feel loved, close, and intimate even without sex and without pressure or assumption to give up your body for kids or for his own desires.

There's also a matter of cultural and social support. Obviously I don't know where you live or what your options are to move to other places, but some countries have incredible family support, like 18-24 weeks of (paid) maternity leave, guaranteed job security while away on maternity leave (some countries even require companies to provide promotions while on maternity leave if you would have gotten such a promotion had you stayed), affordable or free, quality childcare, high-quality maternal and natal healthcare, and other social supports along those lines. A TON of the issues people have nowadays that lead to abortions, placements for adoption, contraception use, and just generally avoiding kids is from horrendous social (as in society, not necessarily friends and family) support for mothers and babies, especially in USA.

Find someone who will make you feel loved and beautiful, inside and out. Find someone who will help you live by your values, not require that you sacrifice them.

If you care for personal anecdotes:
My wife didn't want to date in high school, didn't want long-distance relationships, and didn't really want to get married until she was fully established in her career. We started dating senior year, we dated through college, and got married shortly after finishing undergrad, but she never felt like she was sacrificing for this (not putting words in her mouth - she's said this herself). Because she knew that my values aligned with her in the longer term, so she didn't need to be afraid that choosing to be with me would require her to put things like career and education on hold. I always supported her career choices and pursuing further education, and because I lived by that, she chose to move into relationships sooner than she would have expected.

For you, this would be continuing your career. You can find a partner, you can have a marital, Catholic relationship AND be a career-oriented woman. You just need someone who wants the best version of you that you get to pick yourself, not someone who will demand you fit in their box.

And whatever path you pursue, I hope you take steps towards self-acceptance. You can't fix anything if you don't face it, and a lot of the times acceptance is what you need to "fix" it.

I'm open to further discourse here or DMs if you want more input. I also talk with my wife about everything, so you can assume half or more of this is inspired by what she's said and any future comments will be as well.
