Seesaw;
I am so very sorry that you are feeling discouraged and low. I don’t have anything helpful to say as I am not even able to get out of my house, forget about driving more than 4 minutes.... I wish I could help but if i had anything profound to say, besides how sorry I am that you are going through this, I would.... but I have hit rock bottom myself.
May be this is mostly due to the fact that you have been working a lot and that you are not in your own surroundings? may be there were multiple things that were triggering you throughout your stay and being around people brought those up? Lets hope that this is the case for you and that you will feel better once you return to your own space.
Please don't be so discouraged by this incident. It may get better in time.
