I'm a big advocate of psychotherapy. Most people, I think, could benefit from at least one short stint sitting across from a professional listener and talking about how they feel. There are lots of reasons why I believe this. The biggest reason, apart from my own positive experience*, is this: your shrink is on your side.
It is helpful, sometimes extremely, to talk to your best friend about what is bothering you. It is fundamental that you talk to your spouse about such things. And only your mother or father can bring that certain perspective in times of distress. But each of these people, no matter how well meaning, has a history with you. They, whether they even know it or not, have ulterior motives. That is not to say those motives are harmful or unproductive or necessarily negative, but because you have a relationship with these people that is based on all sorts of factors and emotions and months or years of experiences, how they react may not always be what you need.
One really, really good reason to talk to a therapist is because he has no agenda except to see to it that you are well. He is on your team, and your team alone. He has fresh perspective and no ties to you outside that 50 minute window, and he'll tell you exactly how it is, unshaded by anything peripheral.
He is your number one cheerleader. He will call you on your excuses. He will validate you when you rightly feel fucked over, and he will kindly inform you that what you are feeling isn't crazy, it's incredibly normal. Or maybe he will tell you you're crazy, but he won't use those words, and even better, he'll let you know that your crazy is fixable.
If you are thinking of seeing a therapist, I can't recommend enough that you do. Every damn body can use unbiased support uncolored by bullshit.
