Do I tell them or not?

I just started dating this REALLY great guy. I like him alot. I seem to be more happy around him. But I have alot of shit going on in my life that he has no idea about. I dont want to scare him away, but I feel different around him like I'm not myself. Should I tell him anything?... Thats one person... The other is my friend. Shes worried about me, I can tell. but I dont want her to know anything... all this shit is going on, do I tell them? Please help!

Thanks Jessica!!! That means alot to me...
What do you mean you've been in similar situations. What parts? just curious lol

i think that there is no doubt ur friend should know, as long as shes trustworthy... ur boyfriend well thats ur call if u think he can handle it and if u can trust him that do tell
