Get rid of all the things that don't make me happy

this goal is extremely hard for me and it seems like it should be easy..if something doesnt make u happy then let it go, thats relatively simple but for me its not simple at all..mostly its people who dont make me happy and from last year to this year ive already started to review friendships and relationships and i have let go physically but emotionally im still holding on
for one i have had the same friends for as long as i can remember and for some reason it became drama filled..there were 2 sets of friends one set from church which we were friends since we were babies and the other set is from h.s.
now the friends from church that we have been friends so long got complicated and full of drama, i started last year with all my friends and now im left with only my two friends from h.s. which we’ve always been on again off again friends so i dont kno how long it will last this time
so basically i let go 4 out of 5 of my friends from church
then ive had this crazy, weird on again off again relationship with this guy for the past 7 years and i finally let that go because he wasnt willing to committ and i couldnt take it anymore
with all that said and the fact that i know that it was too much drama to keep in my life..i still miss them
im really comtemplating whether i should let everything go and completely start over when i move atlanta with my son because it seems like he’s all ive got anyway..i dont know its just hard.. i love my old friend and i love the guy that i let go

i have already started to do some garbage removal as far as my life goes and it feels good, but there still are some things and people that i know i need to get rid of which is a bit harder for me.
it seems even though i know that its bad for me i still have some sort of connection with it and it just makes it hard for me to let it go
