Hi, welcome to HCM
Reading your problems it looks somewhat physical and partial mental.
Your obesity , high BP
. , NO child points towards a ovarian pathology like PCOD or insulin
Also you have working stress
which are adding to your physical stress.
I will suggest consult first with gynecologist and do your complete work up like bllod investigations , USG pelvis etc.
ALso meet psychitrist for conselling which will definately help you get rid of suicidal thoughts.
