I'm 25 and I still have imaginary friends

What the title says. I think it's a coping mechanism for being the least relevant friend in every friend group I've been in. Each year has been getting worse and worse as my depression makes it hard to keep in touch with old friendships. Iconstantly find myself daydreaming about hanging out with my imaginary friends and having fun. I struggle with making new friends too because I already know I won't be interesting or memorable enough to stablish a friendship so I don't even try anymore. Today was my birthday and I didn't get any texts or calls from any of my friends, it's the loneliest I've ever felt in years.

If you're reading this and it's your birthday too, I hope you have a exceptionally great day and you get to eat your favorite food and do something you love. If you're reading this and it's not your birthday, I hope you have a great day as well. Thank you for your time.
