Hi rockabyebaby!

Let go and let God.

God grant the serenity to accept the things you can not change, the courage to change the things you can, and the wisdom to know the difference.

You have explained that you value the support of your parents and sister as described in your post.

You know what needs to be done. You have to do what's best for you.

I'm sure you know about the information here at PC. Depression forum has links to online topics of interest, there is a social club that relates to depression, at top of this web are two icons "Conditions" and "Resources". All these lead to more info on depression.

I hope you can go to a therapist. You can return to get support and express your feelings here at PC. If you have any questions, you can ask one of the community liaisons, including myself.
