You are in the dead end. You are lost. The cold white walls seem to grow sharp corners and edges. You have two choices to get out. One - an easy one into the despair of the night(middle left). It is easy for you now, but you know you will be paying for that for a long long time. The other exist is to cut. To open up the wound and let the blood flow(middle bottom to middle right). It will be painful and hard, but at the end you will get the welcoming warm sun of the day(upper right).
