It sounds like you are outgrowing old, damaging relationships. Growth hurts, no doubt, but we can find peace in the fact that every brick you remove from the foundation of an unhealthy relationship, you are placing in the foundation of your new self. With these boundaries you are strengthening your own house, and you are making room for the future relationships that will make your house a home. The work is laborious... we sweat, we develop callouses, sometimes we bleed, sometimes we cry... but every movement done in the name of this work brings us closer to our true selves. Though it may seem so, you are not truly alone... you are just preparing for the arrival of your true friends.
