Hey there. You're not alone in this for sure. I know so many people who are in the same state of mind, where they can't feel anything and are desperately trying to do anything to feel... you know, something.
Here's an article from Thought Catalog I think you'd relate quite well too. It's also very insightful and hopefully it helps you to a certain extent. Read it HERE. :)
Being someone who has personally gone through the same thing (tbh I'm still trying to get out of it), I can tell you now that it's no use turning to anyone else other than yourself for help. The only thing you CAN get from other people is the motivation to let yourself open up. I'm not saying it's going to be easy, but you can definitely do it. Let just one person in. And, if your situation's similar to mine in any way, it definitely won't be easy, but I trust you'll find the right person to let in your life. Like, really let in your life. The only way to get over it is to just do it. And this is something I'm continuously trying to do, and have been for the past 3 years.
It's not going to be easy, but I promise you it'll be worth it. All the best to the both of us :)
I am also struggling with this feeling. In reaction to it I just isolate. The people I consider friends and acquaintances are the people who I do not talk to. I have gotten out of touch with them. Just got out of a 2-1/2 year relationship with my ex fiancee and I guess I'm just ... getting used to the bachelor life again. I guess my advice would be to fight the impulse to push people away - go to where helpful and understanding people are - or find people who won't be pushed away: who will still talk to you despite your best efforts to the contrary. Thank you for reaching out on here - you've taken steps to make a change in the way things are going. I appreciate your effort.
