What to do after a breakup?

I recently broke up with my boyfriend for various reasons. I love him dearly but I know for my own growth and happiness I could not continue in the relationship. We broke up over 2 months ago and I think about him very day. I used to text him almost 24/7 when not around one another, he was another set of ears. I told him any issues I had at work, family drama, anything funny that happened to me. We talked about absolutely everything. Even if something good happened to me, I didn't feel good untill I told my boyfriend, when he was excited or happy about what I said, then I would feel happy. It brought me joy sharing every detail of my life with him. Even silly things such as how proud I was of how much water I drank that day. Ever since the break up, I feel like I'm just living my life day by day, just waiting for the next day to start. I know I needed to end the relationship because of our differences and how we didn't agree on a future but now I feel very emotional and flat. Nothing seems to give me excitement or happiness. If something funny happens in my life, I don't feel like laughing because I don't have anyone to laugh along with. My question is, how do you occupy your time after a break up? It's lock down where I am, so I'm home 24/7. I don't want to just lay in bed after work untill the next day and repeat. Any suggestions?
