Can a Care-Taker Learn to Take Care of Herself?

I've just had an epiphany, and it's not something I'm particularly pleased to admit. I consider myself an advocate for others. This spirit of advocacy is innate and I believe, God-given. If you want to hear me rant, ask me about the significance of movements like #blacklivesmatter or my newly-discovered yet completely-true white privilege. Ask me how I feel about homelessness, sex-trafficking and children growing up in this country without access to books. Don't even get me started on the FDA or Monsanto. It's so easy for me to see the need to champion the rights of others. As a black and white thinker, it makes sense that I want to right the wrongs of our unfair world and to give everyone an equal shot at their dreams. But here's the problem: I have a really hard time with self-advocacy, hence the epiphany. Looking back today, I've realized that the times I've faced uncomfortable conflict head on, it's because I believed it would benefit someone else, whether it was the person I was confronting, or on whose behalf I was advocating. 
As a caretaker, I've worked hard to let go of the need to do hard things because I am somehow responsible for other peoples decisions. If I confronted someone in the past with great difficulty, I did it because I wanted to protect the next guy from their behavior. But I'm not in charge of their behavior and I do not need to carry responsibility for their future potential infractions just because their current acts have hurt me. (Though I can see how abuse victims following this path are probably making a very understandable mistake). So now that I'm not facing difficult confrontation on behalf of someone else, I'm finding myself hiding from necessary conflict and wallowing in shame as a result. I'm really hurting, guys. And yet, I feel dumb about my big feelings and don't want to have the difficult conversations required to rectify the situation. How incredibly difficult it is to say, "Your behavior, while most likely unintentional, hurt my feelings in a big way and with humility, I ask for your apology because my feelings matter." Agghh!
And yet, I've learned these past few years how incredibly important self-care is. That I deserve love and care as much as anyone else in my family, church and community. That there is no need to apologize for being human, needing space and having needs that require money, time and solitude to meet. And while it's simple enough to drink a cup of tea or serve yourself breakfast first, how hard is it to validate your very real feelings in a difficult situation? (Frankly, I'm being cavalier about the tea and breakfast first, but that was actually really difficult in the beginning). How hard is it to let people love you when you're purposefully exposing "weakness" (big feelings aren't weakness but my shame voice begs to differ) that you just can't seem to rationally contain? This, my friends, is the ultimate self-care act and this care-taker is wrestling, for sure.
