It is all about letting yourself feel emotions and then eventually, finding something for yourself. These were my breakup steps: Weeks 1-3: cry whenever you want and do NOT avoid it. Allow yourself to feel the emotions and tell yourself ‘I feel rubbish, I feel betrayed, I feel sad, but it will all be okay one day if I let myself process this’. Try to process it even if it feels like you’re breaking so that it doesn’t creep back up on you in the future. After that first month, I vowed to myself to find something for me. This was going back to dance classes for myself. I would highly recommend finding a hobby. This might also allow you to meet new people. The best tip I heard which helped me is: you’re sad because they’re the last memory you have, meet new people and do new things so your newest memories aren’t involving them, and create a new life so your present doesn’t involve the past. Basically, you’re sad right now because it’s all you know. Cry, feel it, then a new life.
One small step at a time. Maybe that’s just looking up places to rent. Or researching possible resources that might be available like subsidized housing, childcare, etc. It’s hard but not impossible.
Staying at his parents is toxic for yourself. You need to plan to move out
First you need to create a plan to move out. You can’t move on dealing with the situation everyday. You have to get out so you can move on.
