> If I could live my ideal life – one where I wouldn't have to socialise with people and wouldn't have to work for a living (I'm autistic) – I'm fairly sure I'd be fine with my pointless existence (although maybe incorrectly).
I'm actually very, very similar to you in that way. In fact, a lot of what you just wrote resonates with me strongly. I am not doing what I ever thought I would be when I was younger. Honestly, I don't fault you for feeling the way you do. It really just depends on what you want your life to be like moving forward from where you are now.
I'll say that for me, I find it much easier to make others happy when I feel good as when I'm depressed. But I tend not to fall too deeply into hedonistic spirals, so that may be a key difference. Also, I originally started taking bupropion for depression, but it's supposed to help with cravings and addictive behavior as well.
> an optimal me probably wouldn't be autistic
Maybe... it can manifest differently in everyone. I can't imagine myself not being autistic. It's a horrible thought to me. However, I would give my foot to be free of ADHD - it feels like such a burden. (I haven't been able to try medication for that yet.)
> For what it's worth I used to abuse alcohol and while I was drunk that's exactly how I remember feeling and why I drank
Totally, and the same with, well, other substances. One, specifically, which induces pure euphoria for a few hours and made me wish I could feel that constantly. However, the big difference is that being in that state is clearly not sustainable. You can't feel on top of the world at all times; it wouldn't make sense, it would be exhausting, and it would be unsafe.
The medication I'm on allows me to feel sad, tired, bored, anxious, scared, irritated, and everything else. It's just that those emotions don't overtake my whole being anymore. They're things I feel in response to events in my life, just like happiness isn't something I feel all the time.
I guess a better way to explain it would be that it's giving all my emotions an even playing field. I can still get really down when shitty things happen - this week has been really rough for me, and I'm not having a lot of fun. But I can still get chores done, enjoy little pleasures here and there, make tiny progress on some hobby projects, and basically avoid the devastation from coloring all of my experiences. I don't feel hopeless even though I've had a big setback.
So, I guess that's off topic. I don't know if I'm trying to convince you to try medication again or not. (Definitely wouldn't recommend doing any experimentation with a psychiatrist's supervision and a lot of honesty with yourself.) In terms of what's "right" or "wrong", it's really about what you want for yourself. Happiness, pleasure, and joy aren't the same things. To me happiness is about equal parts joy and satisfaction. There of days where I have a lot of fun and don't feel "happiness" because maybe it was a little empty. There are plenty of days where I don't have very much fun and I feel happiness because I'm with my loved ones.
