@spiderman2 , you really are hard work, you know that? However, in the festive spirit. I'm going to have to snip your posts down too, and try to focus on the core elements, cause there's just too much (respectful) nonsense and irrelevant information to cover otherwise.
Sticking to the facts,
what exactly have you tried regarding a new career path? I don't want to hear about how much you hate your job, I already know that. I don't want to know what hasn't worked either, or where you've not been treated fairly because of experience or qualifications etc.
I want the facts from you, the bullet-points if you will - at this point, I'm only interested in what you've done to change your circumstances, not whether it has or hasn't worked. Try not to go off on a tangent.
Why do you feel the need to hide and/or suppress your feelings? This is where therapy would be useful to you I think; an opportunity for you to actually speak to someone who's unbiased and can read your body language as well as what you're saying.
Exercise isn't the only solution here. Sure, it'll burn calories and with any luck, you'll get a mental buzz about it, but the biggest obsticle when wanting to lose weight is diet, and I'm not talking (or suggesting) that you follow a diet; when I say diet, I mean control what you're eating - less sugar intake, more fruit, nuts, beans, white meat and vegetables.
If you eat right and avoid the snacking, within a few months (yes months, there's no quick fix for this) you'll be amazed in how different you look. I don't know what you're like with snacking, but every time you think about eating a chocolate bar or packet of crisps, do 15 press-ups instead. If you need something to eat, then grab something with natural sugar rather than refined; an apple, a handful of grapes etc.
I'm not remotely religious, and I don't believe in God, but if you do, then somewhere there's a plan for you, right? In your case, God has given you the tools to work your way through life, it's up to you how you choose to use them.
I knew this was going to come up...
I cannot stress enough that a relationship isn't going to be a magical cure. If you have as much hate about the world as you seem to now, that's going to transition to your relationship and it'll break down because of it - and then you'll have something else to feel resentful of. You really need to sort yourself out before you dwell on relationship goals.
You're 31, I'm 33. I've been on a few dates, but I can't say I've ever been in a relationship myself either. I accept that. Sometimes life just doesn't throw you that bone, sometimes until later in life, or sometimes (as much as you're not going to want to accept it) at all. If that is indeed the case, then in order for a fulfilling life, you need to fill your life with other things.
Online dating as you've been told before doesn't work for everyone, and a lot of it is down to whether the user looks the part, not about who they are.
Whether it's Tinder, Plenty of Fish, Match etc, they're all the same, and they are, to be frank, toxic. You're doing yourself no favours being on them as you've rightfully acknowledged, it's knocking down your self esteem. I don't wish to sound harsh either, but if you're portraying yourself on them as you are here, can you really blame women that don't respond or run a mile? You're probably coming across as very needy and/or desperate, and that's never a good look.
I'm going to skip the rest of your first post because, quite frankly, you're blabbering on about women that wont return interest in you, and it's kinda' cringe-worthy to read.
I cannot stress this enough either, but
please use paragraphs. If you're making a long post, write it in such a way that you're speaking. Every time you pause to take a breath or think, that's where you hit return on your keyboard and start a new paragraph. Reading a block wall of text is severely taxing on the eyes.
I also urge you to be specific with your replies too and not simply quote this and reply to everything as one reply, even if that means multiple posts.
