IIN to feel unwanted when friend doesn't answer or return my calls?

I accidentally misread your post and clicked 'not normal' sorry, it is normal the way u feel, though it's not normal of your friend's behavior though it is very common unfortunately. I have to be honest, you can never find a good friend, friends suck and boy if you find a good one hold onto them as there are hardly any in this world :(
I haven't really had similar just had shit friends that back stab, lie and sometime fuk off. So yeah I would say in your case confront this bitch or cut her out of your life.
