A question for the lost boys

I’ve asked this before, but I haven’t gotten an answer as of yet. Is one going through perpetual heartache? Like, the constant feeling of having a knife piercing your heart. It has stayed with me rather than dissipating away. I can’t sleep without taking a painkiller or smoking. Some shortness of breath at times. The only time it really goes away is when I’m at gym/mass physical exertion. I haven’t been to a doctor because WTF would you be doing asking for the cure to heartbreak from a medical professional.

I’ve attended therapy but nothing came from that. Do you guys have any ways of getting rid or at least managing the feeling without taking up destructive measures (drugs, prescribed meds, etc.)?
