We might think we know what is good for us but we really don't. We can't overcome the difficulties in life except with the assistance and help of Allah. The difficulties are there so that we ask Allah to help us overcome them and to know that no one can really help us except Him. We need to ask Him to guide us in order to know how to deal with them in the way that pleases Him. So, ask Allah in Dua to guide you, aid you and help you in whatever difficulty you are going through. Ask Him to remove them from your life or to be able to accept them and be patient.
One of my favorite Duas is a Dua that I give Allah the power to choose for me what is good and give it to me and to decide what is evil for me and to take it away.
