Stress n other. Suggest something.

I am 36 year old man with 5'6" hight and 75kg weight. Job nature traveling and stressful. Having  high BP and from past few years facing gas and acidity problem also. Vegitarian and most of the time skipped my afternoon meal. Mantaly very strong but from few months feeling alone, guilty and looser in life. Even I don't know what I like. Even if some ask me what is my favourite food, movie or actor, what I like or dislike. I have to think twice. Want to change my life style but unable to do the same. Sometime thinking to leave the things behind and go away some unknown place but as having family responsibilities so can't run from that. Thinking too much about  sex but in real life  never certified. Please suggest something. Thanks
