Test yourself and them

  This is the type of situations where it's unlikely that somebody can guide you to the best outcome for you. Definitely, not a stranger like me. So, let me just summarize what I understood from your story and give you my thoughts. They are no way the guidelines but may be they will help you to decide what you are really looking for and what you need.
  First of all, you need at least try to assess your own state of mind critically. Try to avoid taking drastic decisions if you suspect that you might be in depression or any other condition that might bias your judgment. If you suspect something like this you better seek a professional consultation on this matter. If you are sure that this is not the case then ask yourself - why she or they are avoiding you and not helping your when you ask for help. I believe that good friends could ask such questions straight and expect an honest answer in reply. Then you may try to adjust your behavior to meet certain expectations but don't make it one way street. You better ask for something back and if you don't get what you ask, it is already a good question if she is your friend at all. Friends are either people who don't need any adjustments in their behavior and just match each other or can make certain steps toward each other to improve the friendship. Then, I would never seek and acceptance from a group of people that is ignoring you. You will just hurt your feelings and you will annoy them even more. There are millions of people around you. Take a break. Find new people you are comfortable with or find out which ones out of your company are loyal to you. Make an invitation to everybody for another even that you organize at the same date and time and see what happens. If nobody replies at least with the excuse then you better go on without them.
