I couldn't agree more with
@GaryE depression has been an issue on and off for me most of my life. It is only in my mid 30's that I actually recognised what was going on and got some help.
I have to admit I'm a bit rubbish at taking care of myself, I should be talking to a therapist and getting some extra tools to learn to deal with it. However I make a bunch of excuses because doing that scares the hell out of me. Be better than me
Around Nov last year I started losing interest in everything again, no motivation to partake in any of my many hobbies and spending a lot of time just wasting time and getting into a bit of a negative spiral. Called the doctors and got put back on the same meds again, took a few weeks for them to get working and move past the side effects but feeling a lot more level now. For me I have found that a few months on the meds tends to get me to a good place for quite some time, even after weening back off them again. Just have to always be vigilant for those little signs that things aren't quite processing as they should be.
Just like above I'm a middle aged bloke that "isn't supposed to talk about his feelings and just get on with it". That is such a toxic mindset and so many peoples lives are made a nightmare just because they are too scared to talk about these things and get help. Hence the wall of text here
There is nothing wrong with getting help and using medication if you need to. Your not at fault, its a fix for incorrect brain chemistry. You wouldn't feel bad about wearing glasses to fix an eyesight problem or a support for a sprained joint.
It's also worth pointing out that sometimes find the right medication and dosage can take some trail and error. Also side effects while your body adjusts are super common so its important to stick with it and talk with your doctor.
Back to the more fishy side of this conversation though. Keeping fish is a weird kind of hobby.
There is a lot to learn and its exciting to setup a new tank, doing research, buying new things, setting it up and watching it come together.
But then once that is all finished with it just basically turns into a bit of furniture that needs a little maintenance every so often. That is why multiple tank syndrome is such a common thing, everyone is chasing that buzz of setting up something new.
The issue with MTS though is that there are only so many tanks you can realistically have and eventually the maintenance time required for so many tanks becomes off putting in itself.
Having been in and out of the hobby for a few decades I have gone through having multiple tanks, having breeding setups, going saltwater/reef, etc, etc. No matter what there will always come a point where the "newness" wears off and then it's just work.
My advice is to keep it simple. Limit how many tanks you have, keep fish that you enjoy watching and work out maintenance routines that are quick and easy to follow.
