If you're in the US, there's a high chance there will be an event organized near you as part of the nationwide shutdown initiative.

It's completely predictable that young people today would be more susceptible to fascist beliefs than they have in decades for the same reason more of them are interested in communism than they have been in decades. Contradictions of capitalism are sharper and clearer than they have been in a long time, and people feel the consequences of this in their lives. They understand through their lived experience that something is broken, so they're looking for explanations and alternatives. Fascism is the easier alternative, and it's also important that socialists are organized and prepared to give them a different alternative. A majority of young people in the US support socialism (at least in concept in polls), and communist parties are growing at an unprecendented rate. Young people are just turning into fascists; they're getting radicalized.
My point is that the increased interest in fascism doesn't mean we're doomed. It's a natural response to material conditions, which we should see as an opportunity.
None of this is selfish or childish. It is a common problem that people are treated like they're mature or strong for their age, but you are completely right that people are expecting too much from you, and it sounds like they just don't realize it yet. There's no such thing as being innately mature. You need care appropriate for your developmental stage. It sounds like you have done some amazing work, and in a situation like this, comrades should be supporting your needs. Have you talked with your branch leadership about this? One benefit to working within a party is that you shouldn't have to suffer in silence. In fact, that's how people end up not knowing how to get their needs met for a long time and end up quitting. Please speak with your comrades about how to meet your needs so you can continue organizing long-term in a healthy way.
Are you working within an organization so you have appropriate support and can build morale within the group?
This is hilarious. I think what they're saying in your last image is basically "we are so much better; you just can't tell from the work we do"
This is posted by the ACP, not anything real. It's still a fringe online ideology, nothing like the actual leftist groups doing work. And if there were anything academic or substantial backing this up, they would have to justify claims like the one about its "unprecedented rise," which wouldn't be possible. This is just an attempt at fooling people who don't understand how academia or philosophy work, and it doesn't really matter because, like everything else they do, it's all happening online.
There are lots of anti-imperialist and anti-war organizations. Some are more helpful than others for actually teaching you how to communicate effectively with the working class. PSL is good if you're in the US.
Ultra-leftism can take different forms. Ultra-leftists don't correctly analyze and understand social conditions, so they criticize socialist countries for not already having progressed further toward communism (and often actively oppose them for this reason), and they criticize socialists for speaking to the people in the context of their own social conditions instead of pretending the people are ahead of where they are. They'll say things like that you're not a real socialist if you're not physically fighting agents of the capitalist state or only speaking about core issues like class (instead of what the people care about). They're often fixated on particular revolutionary leaders or particular kinds of direct action instead of real-life organizing based a serious and informed analysis of current social conditions.
Left-Wing Communism: an Infantile Disorder by Lenin is great but may take some extra time and effort and additional resources to understand if you're new to studying topics like this or unfamiliar with Lenin's history. "Infantile" isn't an insult here but a clear statement about how such ideas are based in undeveloped thinking.
The same way you do with the rest of the working class. Most of them oppose this war, and whether they do or don't, your job is to teach them, build popular anti-war energy, and help them understand the class character of what's happening. If you aren't already working within an organization to help you do this, start that process.
The most important thing to know about the PSL is that there's a ton of misinformation and disinformation online from various kinds of sources. Find out for yourself what they believe and how they work by reading their websites and meeting them in real life. You can never trust what you hear online about communists.
It is a PPI and is used to treat GERD and ulcers. It definitely sounds like you have a lot to talk with your doctor about! I hope you get feeling better.
FRSO and PSL are good. Every effective organization will have such allegations and worse made against them. You should see how they work in real life and approach them in good faith before you assume that what you've heard about the most principled communist organizations is true in the most anti-communist country in the world.
