Im new and looking for support

Hi all  

Im new to this  

Im 37 and in march i was diagnosed with breast cancer which has spread to both lungs and collar bone.  ive had chemo, a full mastectomy and 15 sessions of radio.  My cancer is classed as terminal as it can be treated and not cured.  But now my treatment has ended i feel like whats next.  Do i wait for it to start spreading.  I feel like im in limbo. Does anyone else feel the same.
