I've been splitting on my friend on/off for a while now but I figured I could keep it under control. We both have mental illnesses and talk about personal stuff all the time, but this is one thing I'm afraid to share with her for fear of losing her.

I've been getting anxious and angry when she doesn't text back right away or when she doesn't respond with the kind of attention that I want. I'm afraid she's growing distant from me and is losing interest and I don't know whether it's all in my head or not (probably). Lately it's been worse and I feel on the verge of either begging for her reassurance (which I really don't want to do because I'll feel pathetic for it) or cutting her out of my life. What should I do?
