Being a man of the cloth has its own challenges and responsibilities. A lot of the time people are looking to you for encouragement and motivation. You on the other hand have no-one or very few people that you can turn to or talk to. The following words of encouragement for a pastor should be able to help you cope.
You are the one person who really has to practice what they preach. All those messages of hope and encouragement that you have so often said to others, now apply to you. The only difference is that you have no-one to preach the message to you; you have to preach it yourself. Go through some of the messages that you have preached and this time read them as to yourself and not the audience you preach to. These are words of encouragement for a pastor that should help you out.
You can also check out the material that is at christianedification.org and get some inspiration from here. Remember you are the one people turn to when they have their problems. So you need to maintain a positive attitude all the time. I know maintaining a positive attitude and being cheery all the time is not easy. It takes effort and if you work at it long enough you will manage.
Whenever you go through a rough time, you should do your best to endure it and know that it will come to an end. You are after all human and no-one is exempt from facing hardships and problems. You just have to handle yours much better than everyone else. My words of encouragement for a pastor are that preach by example.
