I can breathe but it feel hard and not complete as usual.?

Dyspnea. Do u smoke? Any history of asthma? Any history of allergies? Have u recently been exposed to toxic fumes or smoke from fire? Have u gained weight from fluid build up? Do u use any medications/inhalers for your breathing? Have you been treated for chf? If breathing is very difficult, go to er. Otherwise see fp for thorough history & physical to find the cause of your breathing difficulty & treat it.
Dyspnea. You are dyspneic. The causes of dyspnea range from anxiety to pulmonary and cardiac problems. Given the paucity of data offered, one could not make a diagnosis.
