Good day my Friend,
Thank you for sharing your concern here.
Your inferiority complex is the reason behind such mind set.
In this world everything revolves around 80:20 principles. Means, in every individual including you and.me, 80% things are good and 20% things are not so good( both mentally &physically).
It's all upto us on which side we want to focus. If you focus on 80%, you will accept and feel happy. If you focus on 20%, then you will tolerate and feel unhappy about everything.
In your case, you are only look at 20% side and hence all these feelings, thoughts and mindsets.
Be positive. You can slowly overcome this problem if you're willing to make few changes in your mindset, lifestyle, daily routines, food habbit, and few other recommendations. Are you?
Feel free to reach me online for further assistance and assessment of your physical and mental symptoms to recommend suitable psychotherapy solutions.
Health Tips
Be aware, every individual is unique due to their upbringing, culture, society, lifestyle, environment, food habits, education, family values etc. So there is no one fit solutions for all. General advices, Google search, youtube videos won't give better results in handling individual's emotional disturbance. You need a human touch first to ventilate your feeling and emotions and to identify the issues next. Then suitable solutions and therapies plan can be identified jointly.
Appreciate if you can take the next by talking to a counselor/psychologist.
