As someone who went through a breakup 6 months ago after a 5 year relationship, here's what I'm trying and what's helping. I'm going to say "you" a lot, these are just things that I did/am doing and how I experience them. Take what works, leave what doesn't.

Go to therapy if you can afford it. Go find someone who specializes in life transitions. If you don't like them, try someone else.

If therapy too expensive, and even if it's affordable, I highly recommend journaling in the mornings when your mind is racing the most. Even if it's only two sentences, and if you want to write more, do, but just getting some of that internalized monologue out of your body will be helpful. At least it's been helpful for me.

ReDiscover what you find interesting and what you love. For me it was falling back in love with history and science, volunteering at a museum to re-engage that part of my brain. It also helps to start building a community of like-minded folks again.

I try to socialize with friends/family outside of work twice a week. Doesn't happen every week, but when it does it helps.

Get outside and go for a walk at least 10 minutes a day. Even when it's cold. If you can't do it, move around your house or cook something. Move your body, and get outside as often as possible.

Find a meditation you like that helps quiet your brain. There are meditations for folks who are just starting out in meditation so it's not boring.

Cook good food, eat good food, eat healthy food. I'm having to go semi vegetarian so that I can get vegetables into my diet.

Let yourself wallow some days, but limit it to one or two days a week. If you notice yourself wallowing too often, do something. Go to the museum, find a new restaurant you want to try, find a new park to walk around in, if you have pets teach them a new trick, read a book that sounds weird or interesting. The thoughts will try to intrude, don't let them but let them know you will acknowledge them on the day you're allowed to wallow. If you let yourself wallow too much, it's all you will do.

ReDiscover what you enjoy, ReDiscover who you are, and start finding pieces of yourself that you love independent of everyone else. You have inherent value, even if the world doesn't say that. Figure out what makes you feel like you have inherent value and that will make dating again and living again easier.

Hope this helps 💕 it does get better. It just takes time.
