Welcome to health care magic
I can understand your situation. I appreciate your effort to seek online support.
You are probably suffering from "major depression".
is known to cause depressive symptoms. Even if thyroid status is normal, levothyroxine is helpful in depression. For this consult a psychiatrist
for detailed evaluation. Following treatment strategies would be helpful-
1) Antidepressants like SSRIs (escitalopram, sertarline, paroxetine etc)
2) Antianxiety agents
like clonazepam, lorazepam, alprazolam etc
3) Psychotherapy/ Counselling sessions
4) Relaxation techniques
like yoga, meditation, deep breathing etc
Hope it helps
