Dissatisfaction in Life

Assalamu Alaikum Brothers and Sisters, I facing a few problems.
1. The major on in Satisfaction to my soul, I don't know why what ever i do I don't feel satisfied. let it be materialistic satisfaction it only lasts for few mins days thats it. Even if i do to someone allah(swt) knows it better but i don't feel that satisfaction deep inside. How much ever i try to keep my self happy and satisfied I feel like there is something missing in my life. I don't understand this.

2. Few years back I used to have a lot of anger, which my parents always told to have control over it, now a days I'm at such a plays where I don't get anger at all. Even if someone abuses me or talks bad about me I simply smile I don't understand why I do it. I hardly get anger but sometimes I get irritated. In one word Patience has increased so much that I feel like i have no emotions these days. When I try to cry I don't get tears, my heart wants to cry but something stops me.

3. Career- I don't know whats happening with me these years, What ever i want to do I'm stopped by something I don't understand if it is good or bad which is stopping me. I feel lack of confidence in my self. Sometimes I feel like im incomplete my mind goes blank. Suppose Im talking to someone I don't understand what Im talking I talking nonsense/meanings.

4. About offering Salah I do offer namaz but i miss them sometimes, I get out of the track and then after a week or so again i start. What i want to say is I cant continue my routine of offering namaz. Some times I feel lonely, I dont feel like going out, I don't feel like doing anything. Before I used to ask my parents what I wanted but now things are different I dnt like anything nor I ask for anything. I hard like something these days. Please Help me.
