Work on yourself, you must be so tired and drained why not do a spa day or just take a long shower, work on yourself. Give yourself time. I hope you feel better soon
Nah but fr you should take this oppurtunity to focus on yourself and improve your ability to be in a relationship. Realize that it wasn't your fault and accept it for what it is. Take it as a learning experience, not a burden. Realize the red flags so in your next relationship, you can identify them and save yourself before it gets any worse. Because honestly, blaming yourself or others for the breakup isn't going to do anything good for you. Keep your head up and best of luck to you:)
