Lost Interest In Work. Least 45 minutes?

Therapy would certainly help in your case. You have taken the right call by considering it however you as well seem to carry a misconception about the way it's conducted. One session usually lasts from about 45 minutes to 1 hour. Therapy shall go on for as long as you need (Could last for more than 1 session, where consecutive sessions come with a gap for you to practically apply & evaluate the understanding). You have been observing a drop in motivation to get up & start your day. You already are applying a solution which is partially functional/effective. Right now the need is to understand the cause of dropped motivation & to take steps to curb the same. We all need a drive/reason to get up & start our day. It could be the people in our life, aspirations, compulsion or a goal that drives us. We are different with different set of needs driving us. There are times when situations in one's life doesn't match his core needs hence affecting his motivation level. Please go ahead with the planned consultation & do not give up till you bring back your life on a moving track...again. Good Luck..!!
