How about getting off the damned internet and saving a costly bill? But hey, perhaps you're on a plan and are entitled to pay monthly; well then I guess there's nothing you could do about that, but the point is you're wasting your time on this thing unless you're hosting some sort of online class or making websites or graphics for paying customers. I doubt you really have to use it.
Don't be silly, sure crosstitching is nice.. but for the amount of work you put into it, how much do you ACTUALLY expect to be selling it for when it's not even in demand? Be serious. Or are you just looking for the easy way out? You say you MIGHT look into trying to sell them. Are you serious about this at all? Or are you just pulling our legs and wasting our time trying to "reassure" you?
You have a kid, so you have those duties, but could you do something else? How about physically babysitting? You have your own kid so people would understand that you're responsible for a child, you could also bring your child with you for social interaction with the other child if the other parent allows it. Or have the parent drop their child off at your place. You mentioned your father is contributing to you a little, but is there something that other family can do (like look after your child) while you try to find a job that will actually pay?
I admit I don't know the entire situation because you haven't explained everything, so I can't really offer advice.. but what I've seen from these posts it just looks to me like you're trying to grab some quick cash- and for an amount of cash you should've probably already had in case your poor child gets sick and needs medical attention and/or prescriptions.
I admit I also don't know your financial situation, but you have a LOT of responsibilities on your hands that I personally don't think you're taking serious (for christ's sake you're asking how you can get rent money from people a pokemon forum filled with 15-year olds!) Try a job site, or money-saving site. Try sites where you can get free coupons for products you use daily! (Maybe you are doing this already, but come on! Get your resources quickly. The more you dawdle, the more opportunities might pass you by! and the more time you end up wasting!) The point is.. quick cash isn't going to last you forever. You'll have to change your living habits in order to accommodate your new home AND you have to look after a child who will only need more and more as they grow older.
If you really want something, work at it, and don't be lazy. I'm not saying you are, necessarily, but I'm just getting my point across in general. Get your stuff together. I'm not saying this to be a "troll" I'm saying this because I'm trying to be realistic. I'm not an optimist, I'm a realist. Sure I can be harsh in this post, but the fact is we're dealing with YOUR family, YOUR child, and YOUR well-being. Why would I want to feel you BS and put that on the line.
Hope this helps.
