Gurudev, will doing Sudarshan Kriya and regular Sadhana (spiritual practices) solve all my problems?
You first do it and see. If they get solved, then that is good.
At least you will not be at any loss by doing sadhana. It will give you the strength to face those problems and overcome them. You are only going to benefit by doing sadhana. There is no loss or harm that can come to you by doing sadhana.
By sadhana, either your problems will ward off beforehand, or you will gain the strength to solve your problems.
