How do I prevent people from ignoring me?

[neurospecial]

Hello everyone,
I'm looking for constructive ideas and suggestions on what I can do to get the best out of my interactions with people, personally and professionally.

I am very respectful to and communicative with people and I'm always willing to go an extra mile to be of service to others.
The issue is that I notice that people ignore me more often than not especially in communications or interactions where I require something of them.
Some example to provide context:

1. I go into the office and say good morning to colleagues, but most people ignore me and just carry on chatting as though my presence was unnoticed.
2. I ring my mum just to see whether we can chat and she quickly rushes me off the phone citing a flimsy reason.
3. During a health emergency, I ring my now ex and they just won't pick up and won't even acknowledge that they saw my missed calls.
4. I email clients work updates and ask for their feedback but they don't even respond at all.
5. I set up meetings with colleagues, but they don't attend and they don't RSVP to indicate this. They don't even shoot me a message to let me know they won't come; they just won't.
6. Last day at several jobs, and colleagues don't say any farewell. They just don't bring it up. Even managers don't do handovers; they just stop engaging with me weeks before my last day.

7, I had a cancer scare and told a few friends, and they just switched the conversation to something else and never asked what the diagnosis was.

1. I meet men online and agree dates and they cancel on me 5 minutes before meeting time.
2. If something went wrong in my house and I messaged my landlord, he just ignored.

10. I get a new job and text my mentors to ask for references and they just ignore for weeks. 11. I text and call friends and families to check up on them and they don't answer or acknowledge receipt at all. 12. I give gifts to family members and they don't say thank you or with my ex, he'd trash it as soon as I walked out of the door.

These are my experiences and I could go on and on. I'm highly educated, and present myself properly. I portray confidence on the outside but on the inside, these things have slowly shattered my self esteem. I feel that people don't see me as someone to reckon with hence why they can't be bothered to engage with me until they've left it for weeks to months or never.

Does anyone experience something similar? Any advice on what I can do to be someone who people want to reckon with?
I've noticed I've begin to distance myself from people in order for them not to have any opportunity to ignore me. But I know I need people. Does anyone have any advice?
What can I do to get good responses from people?

Thank you.

Hi OP, I am surprised no one replied to this thread - I would move it to AIBU, so it gets traffic it deserves. With work examples, I would just say that you were very unlucky with horrible colleagues. I worked in a commercial sector and then in science / education and the difference in culture is astonishing. But even then I have to constantly chase many colleagues ('I wondered if you had a chance to read my email', 'Just nudging this to the top of your inbox'). Same goes with many services you buy actually, we had to constantly chase banks, solicitors, hospitals so this does not sound unusual to me. Same for mentors etc. - people do take really long to reply sometimes, especially if you are not chasing them.

However, it does strike me as odd about friends and your mum. Are you close with them? I went through a cancer scare too and can say that friends that I was close to always followed up as much as their busy family lives allowed, whereas others didn't. So I would probably try to get to a bottom of your interactions with friends / family first. Do you like spending time with them? Do you have fun together? Also, I feel like speaking to a counsellor might help - try SHOUT (https://giveusashout.org/) service as they can redirect you where appropriate and perhaps there are free of charge or low cost therapists available. But I also hope that if you repost in AIBU, you might get better feedback than from me, I realise that this hasnt been extremely helpful.

I also just want to bump for you, this thread deserves attention but this is a parenting board so I guess this is why nobody replied yet

Thank you for taking time to respond @Wobblyheart
That's very kind of you. And thank you for the reassurance and for pointing out SHOUT. And to answer your question, the relationships with friends and mother are tricky. I'm always the fixer people come to to feel better or sort out their needs, and somehow I can't find them when I need them even for a simple chat.

I guessed I posted this in the wrong category so I already reposted in the AIBU category and I got some very helpful feedback and advice that I intend to apply in my everyday life:

I'm sure there'd be someone out there who'll find some people's insight and suggestions useful.
