OP, people aren't being hard on you because you are new, it's because of how you've been since you joined. The first few days you spammed the forum with threads, you spammed people's PMs about finding SN and were aggressive and demanding about them telling you. That set up distrust and resentment. Then you asked a lot of basic questions about methods, questions about VAT, questions about what part of the house you should suicide in, now a question about what you should do about this note idea. It's your suicide, your note, your life, we don't own that and it doesn't seem like you do, either, so it's frustrating.
Do you know why babies cry? To be irritating enough that someone will give attention to their needs. When an adult had needs and cries, and other adults can't fix their problems but the adult keeps crying, it gets really irritating and frustrating. Try listening to a youtube video of a baby incessantly crying and see how you physically and emotionally feel; I bet you'll want to turn it off, and if you can't, then you're really going to get frustrated!
You're an adult. There are things you have to figure out for yourself. You haven't been asking for support, you've been consistently asking others to figure things out for you and make decisions for you. From the outside, it begins to feel like you're jumping up and down and yelling, "Pay attention to me and fix everything for me!!!!" We don't do that here. It's a pro-choice support site for adults, not a fast-food drive-thru for instant solutions, nor a daycare center for children who can't take care of themselves.
That's just my direct and honest opinion. That may not fit with how people communicate in your culture. I'm not showing you disrespect, I'm showing you the respect of honesty so that you can stop suffering in this shared space and get along if that's what you seek. Most of us here are Westerners, our culture functions differently from Latin cultures, we communicate more directly and we tend to expect each other to do basic things for ourselves. If you have a learning disability some other kind of disability, we still can't take responsibility for your suicide or anything to do with it.
All that said, I do feel like you've been getting unfairly harassed in this thread, even some bullying. If you think this has been happening, then you can take ownership of this problem and report it to the mods.
But moving forward, if you want to be treated well and to get along, because most of us would want to also get along with you and with each other,, then you need to treat others well by not harassing them or making demands, and by researching answers to your wants and your questions instead of asking like a child who doesn't know how to use the internet or do anything for themselves. You can also get more support by giving support. You're not the only person on the forum who is in a sea of shit. If you give a little genuine attention and compassion to others who are also in seas of shit by visiting their threads and offering a hug or advice you think you can capably give, then they will be more likely to be reciprocal, to care about your threads, and to give you attention and compassion in return. If you're not in a place that you can offer these things to others, that's okay, but you are an adult and have to do some basic things for yourself, or your wants and needs become too taxing for others in their own seas of shit.
I sincerely hope there was some advice in this comment that helped you. If not, that's okay. I tried. I approached you in good faith, and I leave it to you to do with my words whatever you decide. If something was in error or didn't serve, toss it out. If it was too direct and not soft or comforting enough, so that you can't hear my logic, well, I tried. I was as clear as I could be, and I offered advice to help you, not push you down further in the sea of shit.
