TrickyTree. No way are you a failure. Not one single bit. None of us on this thread are. You are trying to take care of your mental health, that is very brave and all of us know how hard it is. In your position I’m sure I would be a total mess, it’s been hard enough to take sertraline never mind transition to another AD.
Your HR will have to say along the lines of that and as usual, people that haven’t suffered with crippling anxiety and depression just don’t understand what it’s like.
You are under a huge amount of pressure, raising your wee boy on your own and working. Taking time off to ensure you can get well enough to do both is not failing, it’s good self care and an important part of learning how to stop relapses.
I really think you should take time off and focus on resting, trying to eat and spending time with your boy.
I was a lone parent for 7 years with my four and working too. I’ve had two episodes of severe depression, we cannot do it all.
Whilst you are trying every day to work and raise your son, there is no way you are a failure and you need to tell yourself that. This will not last forever, it’s just taking a bit of time to find the right meds’ and dosage for you. Hang on in there and most of all, be kind to yourself.
