Krishna, I am so sorry you are having such a difficult time. Please do not do anything to harm yourself. Reach out to someone. Call a crisis hotline, talk to your doctor right away, find a counselor, talk to a friend....Anything but end your precious life. Because it is precious. You are not alone.
There are so many medications, as well as, counseling to help you deal with the pain, the depression and overall feeling of despair. If you are feeling suicidal, then you just haven't found the right combination for you. Keep trying. Don't give up. For me, it wasn't just the medication that helped me, it was my counselor. She helped me to not feel so helpless. Her words really helped me to grieve who I was, which was a healthy working mother and wife. A person who kept the family going. What I am now is different. I've learned to deal with the pain and accept that I can't work because of the illness. I've learned to accept who I am now and love my life. I still have flares 80-90% of the time which include pain, anxiety and depression, but I give myself a break and ride out the storm. I talk with my mom and my husband when I'm having a really, really rough patch. Or I have a couple of very close friends that I talk to. I've learned who I can count on and who is truly there for me.
I pray that you can find that relief and happiness. Please, please do not give up....Gentle hugs to you...
