Thanks for asking.
Overthinking, being sensitive, getting emotional, anticipating about future, etc these are personality traits.
Immense stress can predispose such an individuals into depression.
Regarding you, I would suggest to consult a psychiatrist as he/she can understand the whole history, examine you, and if needed would advice treatment and suitable therapy.
Alternatively, you can also consult me online for detail and comprehensive solution. I will need to ask you few questions and obtain more information.
