Hello Paola,
I can see you are new on this platform. First of all, I'd recommend you exercise caution wrt sharing your phone number or Skype account lightly, just in case. Needles to say, just like in any other social media platform, there are also some bad people lurking here (hopefully they are just a few).
Secondly, though I'm not a native speaker and I think that, at your current level, you'd benefit the most from native speakers or at least people with a C2 competency, please have a look at my profile. You can send me a message through the "message" button if you so wish.
Best regards.
