I thought I would somethings to what everyone else is saying. I am going through exactly what you are speaking of. The thing with me is I was already saved in Christ when I faultered with my own weakness. Because somethings were never addressed after I gave me life to God, they resurfaced at stressful moments in my life. To make a long story short I said somethings about a very close sister in Christ (we lived together for 6 years, and have not went a day without talking to each other since we met). The very people I called my self venting to (also sisters in Christ) decided to go t her and tell all I said and omit what they said. After they felt they had done the right thing they decided to call ameeting with the pastor of our church, themselves, me roommate and myself to confront me.
Well the Lord prepared me and said to take responsibility for what I said repent to Him and apologize to the one I spoke about, without accusing them of what they said which would only do more damage and bring up more hurtful things. They all said they forgave me and thee loved me and was concerned about how I would react to this and not to stop being their friend/sister.
Well they all abandoned me. My sister no longer speaks to me, we no longer live together, and she will not let me interact with her children (my nieces) at all. But I chose to forgive them. Christ has forgivien me for doing much worse to Him, why would I harbor something so mediocre towards people I really love. Yes the devil speaks that they abandoned me when I really needed them, they never loved me, they don't care that they have turned your life upside down and torn apart your family.... But we are all human, mistakes happen, we can all be used by the enemy and them be accused of the very use he used us for. Love covers a mutitude of sin, my love is greater than their sin and vice versa (some people take a while to learn this). But we are to imitate Christ until these things no longer take thought but are automatic.
Yes it hurts, at times I get lonely ALL my friends in Christ have turned from me, but this does not define who I am. I had to forgive myself first off, then forgive them. And remember our fight is not with flesh but the spirits that cause the flesh to do things contrary to Christ and His teachings. Do the opposite of what the devil wants you to do (this is a process), if he says to not speak to them-I speak, don't pray for them-I pray, to curse them-I bless them. It is all based on our willing mind and heart. Read books on forgiveness, Charls Stanley has a great one called The Gift of Forgiveness. This really helped me understand what forgiveness is and what unforgiveness can do to you, it takes a conscious effort and the UNCONDITINAL love of Christ. I hope this helps at all
