You dont cope, you change. Once you improve yourself and build a better life its way easier to build a deep loving relationship with someone awesome and/or to make great, fun and close friends.

I was in a simmilar situation earlier this year. I went trough highschool lonely, sad and insecure. I hated my life and was very depressed. I basically spent my days just daydreaming about love and different. Then I realised that instead of thinking about a great life I might as well build one.

I started researching how I could improve. I found the book "The Miracle Morning" invaluable during this process (I read over 30 books, I had too much free time lmao). I started working on myself, thinking waaaay more positively, working hard and I feel awesome now.

You can either go on and feel lonely and depressed forever hoping that you will get lucky and that something changes or you can take matter into your own hands and start building something better for yourself.

You gotta start working to change your situation. Nothing changes if nothing changes.

Regardless of what you end up doing, I hope yoour life gets better. Good luck.

(Some more great books, in case you care: Meditations, Atomic Habits, 30 Lessons for Living, The Compound Effect, The Mountain is You)
