Will I ever be the person I want to be?

I’m feeling beyond defeated. My backstory; I was diagnosed with ADHD at age five. I’m now 28. I’ve been on stimulants for most of my life which for many years worked very well for me. Recently over the past year or so (maybe even two years?) my ADHD “superpowers” have ceased to exist. I used to be able to take my medication and be creative, productive, inspired, I could feel fulfilled and happy. Now, I take it and still sit staring at the things I have to do, things I want to do, and can’t make myself move. I have been trying different doses/combinations of meds with my doctor over the past year. Now, I’m on 60mg of adderall IR that I take in 10-20mg doses throughout the day. I had a baby last year. Got married the year before. Graduated college and started my career two years before that. This is supposed to be the best time of my life and I can’t enjoy it. I feel hollow. I feel like something in me has gone out, a spark has been doused in water.

I eat like crap because I can’t motivate myself to take care of my body. Can’t motivate myself to exercise (I used to run frequently). Before you say it, yes I’m on antidepressants, 75mg of venlafaxine.

Is this just a season of life I’m in? Is this postpartum hormones? Has anyone been in this position and gotten back to their sparkly self?
