I need actual help

I’m so mentally drained from all this bs. I realise that I always be there for them and always make gifts and act nice but don’t get the same back. I invest my time and energy and just got used for that. I make them as my priority. I usually get zero notifications form people and when I start to talk to someone I give my all to them and when I see that I’m just there when needed it fucks me up. Im not even ugly or shit like that. I’m 185/6’1 and I’ve had relationships before but holy shit. I deleted TikTok 2 days ago. I had like 7h daily on it and I just doom scrolled all day because I had no one to talk to or go outside with. I used to watch her reposts all of the time to the point where I memorised all of them. We used to keep a streak but after I deleted the app she texted asking if there’s any problem with me because I left her on sent for 2 days(still haven’t replied). She will ask me why won’t I reply tomorrow at the gym so I hope things go well. After deleting the app I have too much free time like I don’t know what to do. I spent 2h in Gemini and 2h on games and other bs today. I’m tired man.
I’m sorry you have to go through this right now, but honestly the only thing you need to do is forget about that girl and stop thinking about her… like she was never even there
I understand your desire to be loved by someone..but u know that same love and energy can come not only from other people, but from yourself too, right?
u said you go to the gym besides that, you could just go on walks alone somewhere where there’s lots of greenery and sunlight, spend time with yourself, learn something new. You’re young, u have loot of free time.. read books, any kind honestly I can even give you recommendations if you want (my dad literally gave my brothers a whole list of books every man ā€œmustā€ read ā˜ ļø)
u could also develop some skill that you can monetize later. Maybe you enjoy editing videos, design, or something else?

Ii don’t know the full situation, but maybe people don’t give you back the same love you give them because they see that you don’t really value yourself enough… and maybe you give love in a way that’s not even good for you. Think about that..

but honestly? Maybe people/girls are scared to talk to you because they think u r too good for them?)
