Hello Friend, Good that you are seeking a help here. You symptoms are sign of depression. You may be over thinking about any past bad incidents or any relationship issues or careers etc. As body and mind are interlinked, it may cause bodily disturbances like headaches, digestion issue, sleeplessness, body pain etc. No worries, it's like any other physical illness and can be treated through counseling session and few lifestyle changes. Reach out to me online for further evaluation and recommendation..
