I am not going to tell you to keep doing something that makes you unhappy - however, I can tell you that eventually your tank will find a balance and it will be much easier to keep it looking 'nice'.
The problem with this hobby is that it is not as easy as it appears on the surface. People see the dozens of tanks in a store, or posts on forums like this where tanks are pristine and carefully prepped for a picture. Keeping a tank in that state absolutely requires experience and time.
You've already identified your beginner mistakes. That's a great step in the right direction. I can guarantee you that most of us here have made a similar mistake at one point. It definitely feels terrible, but how else will you learn?
I feel like your biggest weakness right now is simply time in the hobby. Two months is not a lot of time. It is certainly enough to establish a tank - in fact, an experienced aquarium owner can probably get the tank fully setup up and grown in during that period. But newcomers will have growing pains.
Here's my journey - I think it will make you feel better that other people have struggled.
Start: April 2016 1. Wanted a shrimp ecosystem. Small 2G bowl that was setup using the Walstad Method. Bought all supplies, set it up, looked great.
Two weeks later, entire system failed. No idea why. I asked around various forums and had no luck. Knowing what I do know, I assume that the plants were getting a different setup of nutrients and lighting and could not make the adjustment, started rotting, and then spiked the water. Still don't know though, because I didn't know about water test kits at the time.
Reset. Simplified the bowl and bought a betta for it. Hind-site! What a mistake! 2G is nowhere near enough for a betta, and I learned my lesson the hard way - my fish passed away in less than two weeks. At this point, I discover this subreddit. Realize I was completely misinformed about the hobby.
Setup 5G filtered and heated aquarium for a shrimp and snail tank. Tank does really well for a month.
Planaria and hydra outbreak because of a plant shipment that was contaminated from a certain popular online vendor. If you try looking up planaria/hydra and shrimp, you'll find all sorts of information that disagrees with other sources. Some say they kill baby shrimp, some say the toxins they produce can kill a colony, some say they are harmless. Well, I do not take the risk and I use Fenbendazole to kill them off. I know that my Nerite snail is at risk to the Fenbendazole, so I take it out for 2 weeks. All the hydra gets killed, but the planaria are unaffected. I had been doing 25% water changes every day while dosing, so I figured the water was cleared of the Fenbendazole. Wrong - Fenbendazole lingers for MONTHS. My Nerite snail could never recover and eventually died.
Two more months pass. Tank is doing well, and the shrimp are having shrimplets. Suddenly my colony gets a bacterial infection. From where? I had not changed a single thing about the setup. It takes my shrimp colony from about 50 to what I thought were 5 or 6.
Bought a Scarlet Badis, giving up on shrimp. Scarlet Badis does really well for a few weeks. Suddenly I cannot find him. Searched the entire tank, did a full search to find him. Turns out he cleared a 2inch waterline gap and jumped out of the tank.
Tank was now void of fauna - or so I thought. Turns out I had a few stowaway shrimp...and they were healthy? Completely fine, no symptoms of the infection. Now they've re-established my tank and I have a few adults, 2 of which are berried.
If you're still with me by this points, you'll note that I've lost: countless shrimp, a Betta, a Nerite Snail, and a Scarlet Badis.
There's a very good chance that the infection comes back. But you know what? I am still trying, because watching those shrimp for a few minutes every day gives me a lot of joy. All those mistakes I made that led to the deaths, I have learned a lot from them. They're mistakes I won't make again. I will surely make mistakes in the future, but all the prep in the world can make you perfect in any hobby.
My tank is immensely easier to maintain now that it is stable. Now it's really just water changes, the occasional supplement or additive, and a plant trimming.
If you think that you would enjoy the hobby once your tank stabilizes, I would say stick with it - even if it means losing a few fauna.
