Really need relationship advice please

My girlfriend has been trying to communicate for a few weeks of me being overwhelming with affection and not enough random conversations outside of our relationship. At the same time she's going through many other stresses in life but the whole time has wanted me there with her to help, comfort, and hangout. She has brought up all the serious talks for relationship first and has said many times how in love with me she is. But now all her affection this past week has retracted. We still barely talk but she mentioned ideas of things to do together but no affection. She's currently needing space today and no talking until maybe tomorrow she said to hangout possibly. I'm trying to work on understanding what she needs but also grow the relationship past this hurdle of our relationship and the external stress factors in her life. I just want her to feel relaxed around me again and want me around rather than distancing.

The best thing you have to do is talk to her. Tell her exactly what you wrote. That you like her and care about her. That you feel she is going away and you don't want that. Trust yourself. Talk to her.

It's so difficult to come around to open up and talk. I'm afraid ill push her away because she is overwhelmed by everything in life and anxiety and some depression and naturally introvert. But i care a great deal about her and our relationship. It's a different feeling for me and I haven't came across someone with the qualities i see in her and want in a partner. Is there no other advice to help bring her to comfort with me and want me around more or talk to more at least?

Oh and the space has started Sunday 4 days ago now and no improvement. But she's been asking for balancing the affection for 3 weeks. I just didn't fully understand and feel like a dork and I didn't mean to make her feel unheard and that hurts me.
