Why do I feel like nobody can help me and why do reject them even when they try their best to help and support me?

For me, there have been times when I thought I was beyond saving and felt it would be easier to simply give up. So because of that belief, the efforts of others seemed like a waste of time, and I wasn't interested in receiving help. And then at other times, there was a part of me that was proud, too full of hubris to want to accept the help of others. And hey, the fact that you're asking this question means you've noticed others do care about you and you're conscious of when you reject their support. I hope this helps you find your answer.

You may feel like nobody can help you at the moment and that letting people in will only break you more. But trust me, shutting people out is the last thing you ever want to do. For once you shut everyone out, no one will want to try and get let in. Of course they will still love you and will never give up on you, but shutting them out will not get you any closer to recovery. Let people in even if it seeems impossible at first. It will be worth it when you need a hug or a shoulder to cry on. Please don't shut out the world.

Sometimes its in our human nature to think we can, or even HAVE TO, deal with bad experiences ourselves, but this is not the case. This is often because we are, sometimes unconsciously, afraid of their reactions to what we tell them. It's a totally normal reaction to have.

I don't want to become too attached to someone that may turn on me or leave me after i have become desperate for their help and affections.

You may feel like nobody can help you and instead reject others help when they tried their best to support you is because you aren't looking for that kind of support so when you reject it you are looking for a more specific help to your problems than they can offer.

I understand how you feel because i have been this way before. For me, it was because i felt worthless and that talking to someone wasn't going to help anything. A few years later i finally start accepting and my life changed. It might also mean that you prefer to keep everything bundled up on the inside, scared of secrets or personal things being leaked out.

Sometimes you need time for yourself, personal space is always important. And it's okay if you feel like you can do your best to help yourself :)

I think there might be an element of your character that might not trust peoples intentions. You might have been burnt before so you're trying to become self-sufficient. I was once told "we are not a monopoly of knowledge." If you want better for yourself you'll take the olive branch. If you want to be stagnant you can continue to self sabotage. However, I can guarantee you'll feel depressed in the future knowing you could have done better if you sught help.

Maybe you just can't change your mindset "nobody can help me", and unconsciously, this paradigm will affect your social life. As you said, you'll reject them even when they try to help you. I suggest you to try to open up yourself to anyone

Having experienced this behavior from both sides I get what you’re saying. Sometimes it can feel like nobody is there however their are many people who do care and are willing to help. Our Emotions sometimes stop us from getting the help that we need. Try to stay calm and really think about the greater good!
