Maybe you are being introduced to a fairly important practice of keeping your mind focused on prayer. At least, if you look at it this way, then you can see it as something helpful instead of something detrimental. If your mind wanders (mine CONSTANTLY wanders!) if you notice it - I've found it very helpful to tell myself "This is life stuff, I am praying, I will deal with life stuff later, I don't have to deal with it now." Then before start back into my prayer - starting the individual prayer over (this in itself, starting the prayer over from the beginning is wonderful for immersing myself in prayer) I say, "I'm sorry for the interruption, Lord, you now have my full attention." This reminds me that I am talking to my God, and He's patiently waiting for me to spend time with me. He wants to spend time with us. He LOVES this time we share with Him.
If you are not GETTING to prayer because something is blocking you - as you say - look at it as a contest, and the prize is your prayer corner. What's his face can't keep you away, it can only introduce it's own feeling of wanting to stay away from what is holy. It's not YOUR feeling - it's IT'S feeling. Remind yourself it isn't YOURS - and it IS LENT - a time for soldiers to hone their skills - and GO PRAY. If that prayer corner were the most important person in your life - and it was the LAST TIME you'd EVER see him/her again. . .what would you really put up with to keep you from him/her. This is your God. . . what are you going to allow to keep you from your God? Your Christ?
When my mind is REALLY wandering I take it as going into a really hard work-out. . . you don't get endurance unless you do it often and COMPLETE the task, so as with training for a race, I'm patient with myself in this. It takes time and effort. You don't develop the necessary muscle to perform a good race overnight.
This is Lent - a time of exercising our souls for our maturity in Christ. So take your lack of focus and desire to pray as a good thing, and use it for the better thing.
