Reading your posts made me feel very sad. You have such a low opinion of yourself when the truth is that you are a person worthy of dignity and respect, the same as anyone else.
I think you're looking at this the wrong way. You've listed deficits rather than strengths, and it's all geared around what you imagine builds your worth.
A healthier approach would be to work on your self esteem. There are so many small ways to do this that won't cost a penny and they will only benefit you.
Then, as your self worth grows, you'll naturally start to have a more optimistic outlook. That's when you'll see opportunities rather than obstacles.
I'm going to list a few things that I hope will be helpful. Please don't view them as a pressure or chore, but do perhaps give one or two of them a go to see if it makes a difference.
1. Mindfulness/meditation
There are free apps aplenty to guide you through a short, daily meditation. It will allow your heart and mind to settle, for anxiety to drop away even if.just for 15mins, and give you a daily boost.
2. Gratitude
This is talked about a lot and to be honest, I don't really like the gratitude journals that are on sale everywhere, it's just another "thing" to buy. But the concept is cool. Even if you just type 3 things into a note on your phone each day, it'll sharpen your focus towards what is working well in your life and give you a break from the drudgery.
3. Treasure your wellbeing.
This means creating a routine that prioritises your health for example, setting a bedtime and wake time that allows you enough rest; sticking to an exercise regime - even 30mins walk a day; and upping your intake of fresh food rather than processed stuff. It needn't be a big deal, any step.in the right direction is a positive.
4. Timetable fun
This is something recommended by Michelle Obama and it's so true. We timetable our chores but we don't make time for fun and so often the days go by in a whirl of tasks and responsibilities. Prioritise your favourite show or a chat with a friend - because you're worth it.
If you are able to do even some of the above, I guarantee that you will feel calmer, more confident and happier.
This is a great time to start making some life goals - long ones and short-term goals.
For example, short-term goal - find a job paying the same for fewer hours then using the extra hours to research careers that may interest you.
Or start applying for higher paying jobs. Then put the additional.earnings, no matter how small, into a savings account towards improving your opportunities.
Make use of all free resources whether they are self-help books from.the library, free apps that you enjoy and/or learn from, free CV updating services- all of that.
Tackle it like you would any important project with lists and timeframes and markers for achievement. Share your goals and achievements with people who care about you. Let them encourage you.
Limit your time with people who criticise and complain; they sap your energy and defeat your hopes.
You are capable of upskilling, getting a job with better benefits and prospects, and creating a nice life for yourself. You just need to start believing it's possible then get on with moving forward, one step at a time.
