I will definitely be praying for you and your family, and I don't like hearing that you're having a hard time.
Mostly rhetorically because you're not accountable to me or anything, but I ask, when was the last time you had Reconciliation? Or Jesus in the Eucharist? I don't know what your daily life is like, what kind of money you have, if you have a car of your own, etc, but I think if you're having a spiritual crisis then what you need is Confession and Daily Bread. If you have the option, I think you should get to as many weekday Masses as you can. I do not presume to tell you how to live your life, but I've fallen away from the faith a number of times, and the only way back is to seek out God's grace, first and foremost in the priceless treasures he has left us.
In regards to being unable to force yourself to pray, my first piece of advice is exactly the same as the above paragraph. The Mass is the greatest prayer of the Church, the center of her life. And you need Reconciliation at least once a month and probably more frequently than that. To receive these two sacraments more frequently can seem like a burden sometimes. The Devil certainly wants us to think ain't nobody got time for that. But you get more out of anything the more time you invest, and God will certainly not be outdone.
The second piece of advice is the treasury of the Church's formal prayers and devotions. If you have trouble praying each day, then start there: the Divine Mercy chaplet, daily rosary, part of the Divine Office, the Angelus, the litany of the Sacred Heart, a devotion to your favorite or patron saint. I have trouble getting myself to pray each day, and this was the solution I found. The Holy Spirit is with His Church and is with you. If you devote yourself to prayer starting (and persevering) with these formal prayers, then informal, spontaneous ones will flow more naturally. "Resist the Devil and he will take flight. Draw near to God and He will draw near to you." -James 4:7b-8a- Pray these prayers, and pray directly to the Holy Spirit asking Him to help you pray (take a look at Romans 8:26). I myself pray the Divine Office as an example. It is another priceless treasure from God. Prayer is God's gift to us, and as today's gospel reading said, "...ask and you will receive..."
If any of this sounds judgemental or something on my part, then it is entirely unintentional. As I've shared before, I've gone through dark times myself. Don't be giving up. Flee to God and rest in Him.
