Having A Feeling Something Good Will Happen?

This isn't completely a story, it's more of a question. I would like to know if anyone can help me out with this and what I am feeling.

I used to be a very happy person, for years. Mind you, I was younger and had a lot less stress. I was in better health, mentally and physically.

Over the past few years, I have gotten worse and worse. I now suffer from depression and anxiety.

My point is, the way I used to feel when I was younger and at my happiest - I remember that feeling so clearly. Sometimes I will sit and think of that time in my life and instantly become so happy. Nothing else feels the way that does to me.

My depression has become better through breathing exercises and meditation, but is still haunting me.

I want to know if anyone has an idea of why I've been having a feeling for a few months now of my future being better? Sometimes I think maybe I'm just hoping for it to be better, so my mind is playing tricks on me, but I'm not sure.

I think about the future and FEEL something strong. As if my life will be okay and that I will be as happy as I was before. I have constant feelings of my future being great, like I will be successful at something or succeed in what it is that I want to do. I do have a few plans in the near future, and I feel as though my mind and body are pushing me to complete my projects.

I hope someone understands what I mean. It's difficult to put into words.

I guess it's like, having a feeling that something bad will happen, except this is the other way around. I've never had this feeling before. It feels so powerful.

Thank you all for reading, and thank you in advance for any help.
