Questioning your own feelings is the reason you suffered so badly with a narcissist.
Your feelings are never wrong; your feelings are an unfettered manifestation of who you are, and who your heart is. Your feelings are the very real, true you - the you that needs to be respected by the people you spend time with, and, most importantly, by you.
Your feelings are all you have. Think about it; you can win the lottery and meet the perfect partner and have wonderful kids and an exciting fulfilling career, but none of it matters or makes life worthwhile if, emotionally, you feel like crap. You can have a low paid job and a tiny house and not be able to find a relationship match, but if you feel chirpy every day, who cares? The feelings are the only bit that matter.
Feelings are signposts. If somebody makes you feel bad, that's a 'keep your distance' signpost. If somebody makes you feel good, that's a 'move closer' signpost.
And your situation right now? You are feeling crappy, and that's a signpost that you need to be looked after and listened to and nurtured and loved. You don't need anybody to do this for you. You can do it yourself. Recognise that the you that says 'Am I normal?' is not listening to and caring for the you that feels things. In fact, she is looking at the you who feels things, and saying 'I think you might be a bit of a wierdo, actually.' That's not a kind attitude to have towards the true you.
Deep down, really, you know that you're a good person. A kind person. And, if there's anything unusual about you, that's not because you're wierd; it's because you're unique. We all have special bits! The asking of the question 'Is it normal to feel the way I do?' is actually asking the question 'Do I think that the me that feels is a wierdo?'
Look after yourself. Not by buying yourself flowers or indulging in a bubble bath, but by listening to and respecting your feelings. By not questioning whether the real you is normal for feeling what she feels. For offering her the acceptance that, ultimately, you were looking for when you met your partner in the first place.
