Seems to me you have two problems....The first being....You are lonely....the second being....you are fat. You CAN do something about both. You sound a lovely person, but in your book that's not enough. So how about writing a different book for yourself. You are the writer, the producer, the star in your own film of life. If you say "you can" you CAN, If you say "you can't" you Can't. It's up to you. There are plenty of people on this thread, who are writing a different script to you, but have had at least one of your problems, ask your self why do you think that is. What are they doing that's different to you ? Some say they are fat, but have 'confidence' and some say they 'don't care' what others think, some of their partners 'love them anyway'. I have been fat and I have been slim, I know which I preferred. I am not happy if I am fat, it has nothing to do with how other's see me, it was all to do with me, and how I felt about me. The only person that can do anything about your situation is you. If I was you, I would start with setting myself some goals to achieve in small chunks, I would do this by writing them down. 1st goal, forget about 'getting a man at this stage. You cannot have a sucessful relationship with anyone, until you have a sucessful relationship with yourself. Put on hold until later.
2nd goal, for the next two weeks change your eating habits...cut down your portions, take a relaxing bath and pamper yourself and see your self in your minds eye being sucessful as you go through the two weeks. Use all your senses, ie feel what you feel see what you see, hear what you hear. See yourself achieving your goal. What the mind can concieve the mind can achieve, it becomes a self fulfilling prophecy. You could lose 4lbs in two weeks if that's what you want.
3rd goal do the same the next two weeks as you did the first two weeks. Then really notice how you feel, do you want to continue feeling a sense of achievement ? Does it make you feel good about yourself.? If the answer is yes... continue in small steps and chunks.
4th goal....Write down what needs to happen for you to stop feeling lonely, what can you do that's realistic, that you could do, that you would like to do, to 'start' to change that situation, in 'small chunks again, slowly, bit by bit.
At the same time as doing the above, start a gratitude journal, and every day at the end of the day, write down three things you are grateful for, simple things, like, I smiled at someone today and they smiled back. I am so glad to be alive, I realized I am young and can do so much with my life.
At the end of the first month, congradulate yourself on how well you've done, and let go of any mistakes or negativity. Do something simple but nice for someone else.
You have now started to change things in a positive way for YOURSELF, no one else, but others will benefit from the new you in so many ways.
I just want to tell you I changed my life at the age of 38 years, I did it for me, I was also lonely like you and unhappy. You have all your life ahead of you, when you change the world changes, you can't change others ie men but you can change you, the rest will change automatically, you will be amazed and delighted. This is sent to you with love xx
