Struggling with Mental Health and Gaslighting in My Relationship

First of all, I’m sorry to hear about what you’re going through. I don’t know all the circumstances, but I know that it can be very easy for the negative thoughts to spiral out of hand especially with any triggers present. I’m no expert in the slightest, but I would definitely recommend that you reach out to a close friend or a counselor at the least. If serious enough, I’d definitely advise going to the ER. Poor mental health has been described to me as an illness by my therapist, which was super helpful to me in illustrating how much it can affect you. I hope this helps at least a little. Take care of yourself and be sure to reach out whenever you need help! You are much loved!
