Hi... I have found meditation to be excellent. Over the past 6 months I have restarted seriously meditating and I love it
Here is a link to buddhanet and its meditation resource page.

Here is a link to e-sangha, which is a buddhist forum. You may not be interested in buddhism, but they have an excellent subforum on meditation with loads of resources and suggestions and they are a good place to chat about your needs

The thing with meditation is that people kinda assume that you need to be calm and grounded to start with, or that you "fail" if you have thoughts in your head while you are doing your practice. But that really isn't the case. Just sit and focus on your breath and note your thought - the good the bad the ugly
Try not to let them "hook" you in, label them as just thinking and return to focusing on your breath. Some people count their inhalations and exhalations, cycling from 1 - 10 and restarting at one when they get distracted by a thought, others just do the same with the out breath or no counting at all. Try and focus on a part of your breathing. Mine is usually the sensation of the air on the tip of my nose as I inhale and exhale.
Posture is really important. I had started meditating at home years ago by myself and found that I was so concerned with being uncomfortable that I really didn't get much benefit. So I did a short course with a buddhist group and found that my meditation was much better after focusing on the practicalities of actually sitting properly. The basics of it is to have your knees below your hips and to prop your butt up on something stable.. like telephone books or a proper meditation cushion. If you are finding that a bit tough going, sit in a chair, but in an upright position.
Meditation has been wonderful for me. Staying with myself and developing a commitment to myself with my meditation, has enabled me to do the same when I am not in a formal sitting. I am far less prone to overeating and binging because I can just stay with myself and my emotions much better these days. Pema Chodron is a female tibetan buddhist who also has excellent audiobooks helping with meditation and addiction.
As you can see this is a fave topic of mine
Sorry the post is so long... I am happy to chat about meditation further if you like.
Many blessings to you as you start
