What country/area do you live in? That will help us to signpost you to suitable services that may help you.
That being said, posting here admitting that you need, and asking for, some help was a brave thing to do and while a small step is quite possibly the most important one. There is help out there wherever you are and while you feel very alone right now I can tell you that people do care and will do whatever they can to help.
There will be ups and downs with this process for sure but keep plugging away at it and the trend will most definitely be positive over the long term. Regardless of what people in your immediate circle may have said, you are definitely worth it and you will get to a better place with different people and a better support network in your life.
