Could Shortness Of Breath Along With Rapid Heart Rate Be Symptoms Of Panic Attack?

Hi, im a 20 year old male and i have been eperiencing mild panic attacks, whenever i am alone, without friends or anybody nearby i get really shaky, my heart races, i get shirtness of breath im unable to think or act properly and i have to calm myself down. I have recently thought about suicide (not that i would do it) but it has been on my mind. Im not usually one to believe in depression or anti-depressants because i have always thought you could get over anything and everything. But this is starting to affect my life.
