OP,

If that makes you want to die, I would see a psychiatrist promptly. Do not delay. In my 20s, I had mild suicidal ideation and I did not see a doctor though I once called a suicide hotline... in my 30s I had a suicide attempt for real. Better safe than sorry - it is abnormal to want to die while being a healthy 25-y-o woman, OK, "uncoupled" but still, healthy and poised. So go get yourself tested.
