I've heard of a snowball effect that many of us seem to experience. For some people leukemia, for example, has been a side effect of other cancer treatment. It's a catch 22. One trouble can lead to the next and the next. It's all connected. For me it's been CML, neuropathy, Bels palsy, vitamin deficiencies and allergic reactions to treatment. It's no wonder we experience anxiety, depression and fatigue! For the anxiety/depression treatment I've been told that Sertraline is effective. I do hope you find relief.
