I have been on fluoxetine for 3 years (had never needed antidepressants before that). I started on 20mg and it made an amazing difference to my mood and ability to function in day to day life. I had very few side effects either.
After about a year it was increased to 40mg as I started having anxiety symptoms as well.
The mental health issues began because of several different stressful situations that were (and some are still ongoing) happening in my life. Most of these are beyond my control at the moment.
In the last couple of months I have noticed that I'm not feeling much of anything. I feel like I'm going through life on autopilot and not able to engage fully with the world or people around me. I avoid feeling painful emotions because I'm concerned I don't have the resources to deal with them. I feel very weary and tired. I have some volunteering responsibilities that are strongly aligned to my interests and that I should feel passionate about, but honestly right now I often feel like I don't care (even though deep down I do) if I miss deadlines or don't show up. At times I am struggling a bit to concentrate at work.
I'm already on a medium dose of antidepressants and I feel like this - I'm worried about how I can feel better. Could increasing the dose help? but then I'd be on a high dose and where do I go from there? Or is there any benefit in exploring changing antidepressant? I'm concerned about that too as I know often side effects can be bad and I was fortunate enough to basically have none with fluoxetine, and what if a different medication isn't as effective for me?
