I’ve been taking sertraline 50mg for 3 years, having suffered from anxiety and depression most of my life. I’ve gone through a period of awful illness and got very low again, having suicidal thoughts and feeling very depressed. My doctor has increased my dose to 100mg about 10 days ago, but I’ve felt worse since - agitated, anxiety horrendous, shaky, bursting into tears randomly, headaches. I know you get this initially when starting sertraline, but does this also occur when you increase the dosage? Thanks in advance.
