Hi sorry for the delay, I just got back from meeting up with my father. We can start pretty much now go ahead and PM me with how much detail you want to go into and I'll help write it with you!

As for positivity, that's something that you'll have to break yourself into. Very rarely do people suddenly turn over and realize the world is a positive wonderful place haha. So the real key is to try and understand what exactly your friend wants from you and how much you want to do. If they seem to want less negativity maybe they're telling you some of the things you say bring down their happy mood. Or maybe they want you to be more supportive. Try to read more into what they want and how much you're willing to change your behavior to make them happy.

I'm a major people pleaser so I tend to go above and beyond to fill people's emotional needs but that doesn't mean you have to. And also, people will always be able to nitpick your behavior no matter how perfect it is so don't take their comments too seriously haha.
