Hey, this sounds like me in my 20s:
I do NOT have bipolar disorder. I do NOT have chronic low mood. I do NOT have lack of emotions. I do NOT have PTSD. I have periods of extreme, unbearable intensity with periods of normal in between. I have relational trauma. Since my issues are intermittent, I cannot for the life of me tell if I am ever helped by anything.
Which lead me to decades of drinking and smoking weed. Diagnosis-wise, my therapist landed on CPTSD. Which isn't recognized in the US. it's (apologies if this offends any folks diagnosed with CPTSD out there) kind of a catch all for folks whose situation could be described as you've described here. Think of it like the IBS of mental health diagnoses. Anyways, the diagnosis doesn't help much.
I am currently in an intensive DBT program. While it has been a lifesaver when I have "simple" problems, it does not touch the intense pain of others.
Are the intense pains the relational trauma you alluded to? Bc that's normal. Not fun, but normal. I won't praddle on and assume a bunch here, but usually deep hurt leads to maladaptive coping mechanisms which kind of regularly create the "simple" problems. Leaves you feeling stuck.
How can I figure this out?
So, there is no magic pill. There might be a better antidepressant. There might not be. I've been on several over the last decade. Landed on one that works. I know it works because I only cry when I am really really upset but I still tear up and have emotions for things like art, etc. my emotions aren't flat. They're under control. That's how I know. Everyone's different.
Here's where folks give up: there is no magic pill. There is a cure, though. It's exercise. I know. I'm sorry. It's awful.
Finding the right med isn't a magic pill. It will get your emotions under control. They're crutches. Not prosthetics. Once you're doing okay-ish, the only thing that's gonna get us chronically down folks feeling better on the regular is exercising on the regular.
I hate gyms. I hate running. I hate working out near people. So, I hike. I drive to a nearby hill and walk up it. Then I walk back down and drive home.
Just like 30 mins of walking every day will genuinely make a massive difference. My pro tip: walk fast enough that you are forced to focus on your breathing. Leave no space for rumination. If you're still ruminating, find a steeper hill or walk faster.
In my 20s, I would have never even read a response that suggested exercise was a piece of the puzzle I was trying to solve. If I never did, I almost certainly wouldnt have made it through my 30s.
