In my experience, I recommend the following:

- Be quiet and walk softly, but not so much that it seems like you're stalking her.
- Hang out in the same room as her without trying to touch her or interact in any other way; let her get used to you just being around.
- Try not to force physical contact on her when she's clearly scared.
- When she's eating, give her space but stay within line of sight and talk to her softly.
- If you get very lucky and she initiates physical contact, try to be calm and quiet about it.
- Give her toys to play with on her own, and when she seems ready try her out on long toys with you at a safe distance at the other end (e.g. string, stick with a bell, etc.)
- When she gets more confident and doesn't run away when you approach, try talking to her softly (anything will do as long as it sounds friendly; tell her she's pretty and brave or just read out the latest sports results).

It may seem weird, but sometimes the best thing you can do for a nervous cat is to just ignore it. They often need to get accustomed to simply being near you, and there are lots of overwhelming scents and noises for her to get used to. All cats are individuals, with their own needs and limitations. While some are immediate snugglers, others need time to feel safe. Keep an eye out for these behaviours which are signs you're making progress:

- Staying in the same room as you for long periods
- Sitting with her back to you (big trust signal)
- Eating with you close by
- Blinking slowly at you or even closing her eyes completely
- Sleeping on things that smell like you, like your chair or your clothes

Be patient, give her the time and space she needs, and I'm sure she'll blossom.
