Hello & Welcome, Heartache402! Glad you joined.

I'm seeing at least three issues here:

• mourning a relationship
• depression
• insomnia/sleep disturbances

All are related, and it may be valuable to take a multidimensional approach to getting to a more comfortable place. Do you have access to medical care and counseling?
