The only way out is...

 The only way out is through. 

How many times are we faced with something that we just wish wouldn't happen? Or that we could just skip ahead and be on the other side of already? There are so many things people experience that bring these feelings out.

Nerves over speaking/performing in front of people.

Booking that appointment with the doctor.

Talking with that loved one about hurt feelings.

Cleaning something (often the bedroom/playroom for the kids...).

Making that move to a new home/job/situation.

It's difficult to find and keep the momentum; often it's that first step that's the most challenging one to make. But here's a trick that's worked for me.

The more you just jump in and get it done, the easier it is the next time. And the time after that. And the time after that.

Picking up the phone and making that call becomes easier the more often you do it. Going through the motions of cleaning/tidying becomes easier when you do it more frequently. Pushing past the funk of that day you just want to have over creates stronger and stronger resilience that makes the funk days farther and farther apart. The longer you put off that seemingly terrible task, the bigger the task seems and the harder it becomes to start (and finish) the task that originally probably wasn't huge at the beginning.

Hence, the only way out of a situation is to go through it. It'll be over eventually, nothing lasts forever even though it may feel interminable, and once it's finished you will have either a sense of accomplishment or a feeling of gratitude that it's finally finished :)
