Suggest me a book that will help me grow and learn to be happy again.

I need to stop being so negative. I get caught in negative spirals from work and stress really badly. The environment and some of the people there aren’t what I would call positive and I’m tried of letting it drag me down every day that I’m there. I want to be able to understand and control my emotions more and not perpetuate the negative cycle. I feel like I’m letting my life pass me by and I’m not living up to my potential because I’m too afraid of change and can’t commit to the hard work of growth and risk taking a new steps to improve my life and be happy again. Procrastination and lack of motivation/conviction are huge problems for me.

I’m in serious need of emotional intelligence, stability and control, especially in the face of frustration situations in predominantly negative environments. I want to learn to be motivated again. I need to learn how to deal with negative thoughts and emotions, especially when everyone around me is also feeling negative. I let myself get so worked up and upset and I just don’t want to be angry over nothing anymore. I want to my self worth not to be tied with my work environment and performance. I want to feel what it’s like to be self confident.

I want to become the person that my wife sees in me. I don’t want to lose her. I want to make her proud and most of all, I want to see that smile of hers more than ever.

tldr; Any recommendations that help with dealing and minimizing negative emotions and feelings impact on my outlook/mood and how to escape from the negative thoughts traps. How to be more mindful, proactive and self confident. How to deal with anger and frustration. Self discipline.
