Transaction net gain/loss

I have a TXid in my wallet that contains multiple transactions (multiple sends and receives). From what I read these are transactions the network creates facilitate splitting/combining multiple inputs/outputs etc. When I gettransaction in the wallet I have I see

gettransaction 3dda59bf9801f88...5498dd7fd1c3f9577963b94
{
  "amount": -17.00000000,
  "fee": 20.00000000,

  "details": [
    {
      "account": "",
      "category": "send",
      "amount": 0.00000000,
      "vout": 0,
      "fee": 20.00000000
    },
    {
      "account": "",
      "address": "GPP7ic67...9TgitCB21r",
      "category": "send",
      "amount": -20.00000000,
      "vout": 1,
      "fee": 20.00000000
    },
    {
      "account": "",
      "address": "GPP7ic67...9TgitCB21r",
      "category": "send",
      "amount": -17.00000000,
      "vout": 2,
      "fee": 20.00000000
    },
    {
      "account": "TestWallet",
      "address": "GPP7ic67...9TgitCB21r",
      "category": "receive",
      "amount": 20.00000000,
      "vout": 1
    }
  ],

So, I'm trying to figure out what the net result of this transaction is. I received -17 and I had 20 fee. Does that mean I net loss 37?
