Hello Biba_yu: I'm sorry you are having such a difficult time.

I also have some chronic pain issues (ruptured disc in the lumbosacral spine that impinges on the sciatic nerve thus sciatica.) I also have Meniere's disease with tinnitus which isn't painful but causes its own set of problems. Over time, I've simply learned to live with it. Fortunately, I guess, I'm an older person. So I don't have any responsibilities such as being a parent or holding down a job.
Since you have some physical / medical concerns, I wondered if you're familiar with PsychCentral's sister website: NeuroTalk? (I'm a member there as well.) There are a lot of members there who have a lot of experience with various physical / medical conditions. If you're not familiar with it, you might check out the boards over there & see if it might be helpful:
