Hi and welcome. You can come and join us in the main "300 +" thread, it has a number on it and the highest number is the current one. It changes every day or so.
I've always had what I considered to be a "hard time losing weight". Over my many years of trying, I tried different things. Some worked better than others. Some did not work at all.
I think that what I've learned is.. for each person, what works is not what might work for YOU. You are an individual body and mind with differences from your mother, sister, friend, etc. I'm not sure if you are male or female so I won't make any assumption. Anyway, I think a lot of people on this board would agree with what I say there.
My advice to you is.. first, go to see a family doctor (if you can afford that, depending on your situation). If you have a family doctor that you do not like, you do have the right to change to another. Make an appointment with this doctor, and tell them you want to lose weight but need help.
If you think this might take some time, I'd suggest that starting right away, keep a daily log of every single morsel you eat. Mark down as much info as you can, like what time you get up, what your life circumstances are (stress, kids, husband, wife, family problems, etc). The more information you can keep, the better they can try to get to the bottom of things. Perhaps you have a medical reason. Perhaps you don't. But with the record of what your pattern is daily for many days, they can at least see what you are eating, and what your life is like. Plus, if the doc is one of those who does not favor people with weight issues (lord knows most of them I personally have met are like that) it will show you are truly looking for help.
the other reason of course that you should visit the doc is that first, it will ensure you are safe to change your caloric intake, in a healthy way. (meaning, there is no medical reason you couldn't change your eating habits) AND it will give you a formal record to look back on in the months to come.
When I started my 'plan' back in late June, I started just this way. I went to see the doc first, and i got blood tests, blood pressure check, height/weight, etc It really helped to get my brain in the right spot.
You can do this.

It is really tough at this weight to think of the big picture, especially if you're having trouble seeing any results. But stick it out, you can overcome it, when you find out why you're not losing.
