At the end of the day. Don’t be so hard on yourself. Celebrate small victories and take care of yourself because you’re worth it!
If you're in the middle of a breakup, or if you're not happy in your relationship, make sure you are talking to someone besides your significant other.
When I was younger and my parents began to struggle with a long protracted divorce, I begged for Jesus/God to help them stay together. I prayed all the time for my dad to stop killing himself with alcohol and cigarettes.
On a good day, I can let that dark thought go. On a bad day, I just want to crawl back in bed and try not to wake up.
