How do I get over this girl?

Anonymous
I've been in a relationship with a very toxic person for 12 years, 10 of those were marriage. she's not who I'm talking about. We divorced 2 years ago.

But do to the ex, I was probably not in my right mind when this happened.

So, I met a girl through some online friends, and we hit it off, and I lost my mind and fell hard. Well, I lost all my online friends simply because I had been fighting with this other friend, and I was justifiability mad at the friend for trivializing our friendship.

The reason this girl stopped talking to me is because I gave her my phone number and told her unwanted to delete the messaging app. I at that point was feeling pretty down about the fight with the other friend. Well, this girl took this as me trivializing our friendship. Everyone then blocked me at the same time.

That was over a month ago, and I'm still thinking about her. I'm depressed all the time and I can't shake this.

How do I get over her, and the whole situation? I am trying to move on but a lot of these people were really important to me.

The girl I liked in particle, I can't stop thinking about and it only makes the depression worse.

Thank you for those of you who have been supportive. It's been a big help so far. If your reaction is "get real relationships" you don't understand the question. These were real relationships. I know these peoples spouses and children's names. These were some randos in the YouTube comment section, we spoke every day, played videogames together, shared hobbies, and stresses, etc. Stop telling me online relationships aren't real.
