How to be alone

I just came out of a long term relationship and have wanted to be alone for a while now. (I've been in relationships since I was a teenager)

But now I'm single I'm struggling to be alone. I keep going on dating apps and getting drawn into talking to boys, but I'd so love to "find myself"

How do I do it though?

You could take an inventory of things that you'd like to do or explore then do them. You could start journaling to find out interesting tidbits about yourself. You could sign up for classes/seminars that interest you. You could start paying attention to what you like/dislike. I guess kind of in a way date yourself for a while. I think it's great that you are looking forward to finding yourself. By "finding yourself" it can only make any future relationships that much stronger or better. Good luck.

I'm sure you had hobbies when you were in a relationship. just enjoy those hobbies.

You remind me of a female friend I know, who after a breakup told me she wants to enjoy her time alone... less than a month passed and she's entered a new relationship.
Well, I don't know how much it fits you, but I'd define that friend as someone who loves males' company. And it's true, she has more male friends than female friends. She even says herself she prefers males over females.
You may want to ask yourself what is the motive of wanting a relationship so much. Not that it's a bad thing, but it's a strong part of you which you seem curious about. And it's also a good way to get to know yourself better, as you've said you want to do.

If holding yourself from being in a relationship is too hard, how about making up for it by writing romance blogs or journals about your past relationships, or your romantic views perhaps? You can turn this into a hobby, and it can keep you in much more company with yourself.

Dont wait on the television or forum to tell you how to redefine yourself to find yourself. Share what went wrong how you grew what moral characters what you think is best at your age in the context of dating. Allow urself to grieve mature that is always happening with several people. Purge out the toxic and accentuate what went right. Take yourself to lunch self care is important get a good movie spruce up your area taking care being alone with anyone having to elevate you will give you fresh start then go from there.
