How to manage depression due to relationship issues?

These kind of problems may occur due to lack of communication within a relationship.

Find out if this is an extreme disturbance leading you to depression. You can go to a psychologist in your nearby area who will assess you through Standard tests and diagnose your issue.

You need to get tested to find out whether it is only a relationship problem or it has developed symptoms of depression

The probable diagnosis is a relationship issue.

I suggest you directly communicate this issue with your partner. Open and direct communication and sharing your thoughts and feelings is the best way to solve relationship problems. If you want a firm decision you can just practice the decision-making exercise: Just take a piece of paper and pen. Write down the pros and cons (positives and negatives) of living in this relationship. Write as many as possible, the more points you make, the better the results of this decision-making brainstorm as much as possible. If you find more positives in living the relationship you will prevent yourself from making any wrong decision. If you find more negatives in a relationship then it will be easy for you to decide on a breakup. If you find yourself so disturbed by the problems that you are unable to do the exercise, just take some counseling sessions with a psychologist who will guide you in the "decision-making process" and solve your problems in a safe environment.

Get help for your issue and solve your problem as soon as possible because I have observed many cases of relationship problems that end up in depression or any other psychological problem. The earlier you take relationship counseling, there is higher the chance of preventing a psychological disorder from hitting your life.

If you feel the need, do take a follow-up session. Best regards.
