Getting into a relationship or seeing someone new right now is putting a bandaid on your pain. It is a distraction, but is it fair to the other person if they aren't fully aware of your situation?
Allow yourself to heal, and feel the emotions and go through the process or it will cause you more issues in the long run. We all want to suppress the pain, anger, and disappointment, but it's a necessary evil in this horrible experience.
Day to day, congratulate yourself on small wins. Holding yourself together takes effort, especially when your life is falling apart and you're coping with a ton of things you never asked for.
Therapy, staying busy, and getting some excercise are all helpful, but in no way do they completely drown out what you're experiencing. It's a daily process. Some days you will be fine, some days you'll feel like you're at the edge of a hypothetical cliff with your toes over the edge wondering why it's all happening.
Every feeling is valid, and the evil TIME is what changes it all. One day, one minute no matter how small will push you in the direction you need to go. None of it is pleasant, but it's part of the process. There's no wrong or right way to get there.
Some get there quickly, others take longer, years or a lifetime. The important part is remember none of this is a reflection of your self worth, or lovability. Don't internalize pain and the death of our dreams, and happily ever after is a bitter pill to swallow.
Everyone here has experienced some part of what you are feeling, directly or indirectly the stories are familiar, the details vary, but you can find inspiration that most heal in time, and many end up happier in time.
Hang in there. Know you're with those that understand, and dry your tears. You are stronger than you think, and we're here to talk to when you need.
((Hugs)))
