Identity problem with respect to Judaism?

you can have a relationship with God at any point in time in your life. The reason you are feeling this way is because God is trying to get your attention and it seems to be working. Being spiritual is an important part of life. God knows what you can handle and if keeping shabbat and other things are too hard right now than don't sweat it. Maybe your just not ready yet. all you do need to do is just talk to God. People take prayer to the extreme when its just a conversation with the Lord. He loves you and get ready for a great relationship with him!!
