Happy birthday Midnightwisher! I really feel for you! Sometimes, everything happens all at once. The problem is when bad things are happening all at once (and this happens to just about everyone). On the flip side, sometimes you get lucky and good things happen all at once.
Let's focus on the positive! That way, you'll attract more positivity into your life. I really find that to be true. First, you got rid of that no-good, abuse husband! That is really the most important thing. If someone had asked you a few years ago what was priority number one, I"ll bet you would have wished for that one first and your wish did come true.
The friends? It's impossible for me to guess what happened, but I do think it's important to invite people. I have a mother in law who complains a lot and she really attracts negative things. I won't bore you with the details but I think you should try to invite them for some fun activities.
Sometimes, when we make changes to our lives, people have a hard time with that so if you're getting healthy and losing weight then people don't necessarily like it. Why not join a workout group or maybe find a book club? Do you belong to a gym or a church? Maybe you can volunteer? I just met a woman who has no family around and when I asked her what she's doing for Thanksgiving, I felt bad for her when she told me that she never has anyone to spend it with but then she turned it around and told me she volunteers at a mission during Thanksgiving and Christmas every year. She has also adopted a dog to keep her company. That's an amazing thing to do! I'm not saying that you need to adopt a dog (although a dog park is also a great place to make friends), but that sometimes if you get out there and help others in some way, you can feel so good and that attracts people to want to spend time with you.
Finally, let me say that maybe those old friends weren't that great? Maybe they are, but if they're not, then it's a good thing to kick 'em to the curb and find yourself some quality people.
Happy bday to you!
