I also struggle with the same things. I’ve been on antidepressants (which is focused on anxiety and depression ) since 2 years back. And i started my adhd medication this summer (at the psych ward).
I don’t really know if the antidepressant worked for me, but i noticed a clear improvement with adhd meds (started with the adhd meds while still on antidep). I believe that the adhd meds helps a lot with keeping my thoughts “slower” and less crazy. Cuz i usually (without meds) get stuck on a thoughts in a way that it just keeps coming around in high speed. I usually describe it as my mind going 500 km/h. But with adhd meds, it is now down to maybe 200 instead. So the negative thoughts and spirals isn’t moving as fast downward.
I don’t really think that it changed my personality or my traits. I’m still me, but not as worried. I’ve also been doing a lot more during these years to find out what works for me (besides the medication). And i believe that i definitely needed both medication and a deeper understanding of my self and my needs.
I’ve just started to slowly scale down and eventually stop taking my antidepressants for a little while (following my psychiatrist recommendation) because they (and i) want me to try another one and see if it works better than the one i’ve been talking. So right now i’m without antidepressants, maybe i can come back to this post and tell you if it’s any different with just the adhd medication.
Sorry for the extreme length of this comment, i just really wanted you to understand!
