I was in a terrible breakup and i blame myself for everything?

Primary care doctor: There are many signs that may suggest depression, such as: feelings of sadness or hopelessness, angry outbursts or irritability, loss of interest in normal activities, sleep disturbances, tiredness or a lack of energy, either weight gain or weight loss due to appetite changes, anxiety or restlessness, slowed thinking, feeling worthless, etc... Seeing one's primary care doctor is a good start.

Always 2 sides: Every relationship between 2 people is complicated and has 2 sides, so you probably shouldn’t blame yourself for 100% of the breakup, as that makes everything worse. A wise counselor or Dr. can help, as can turning to the Lord, the Wonderful Counselor, and consider humbly asking forgiveness from the other person where appropriate. Try to eat well, exercise, sleep, and refocus.
