Your post really stuck with me because i'm basically doing the exact same thing right now!
I am also going through a process of fading out people who bring down my vibe. So i know the feeling of having to spend time alone. But i have faith that better people will come into my life shortly.
I just deactivated my facebook acount last week because i found myself wasting too much time on there and it really wasn't added anything to my life. Instead i've turned my focus to visualizing/meditating, things that are better me!
The things you are trying to manifest are also the same as me! better friendships, relationship, success ... Its nice to know there is someone out there trying to do the same.
Good luck and keep up the good work! I'll be interested to see how everything goes!
