I have read your post,one part of it tells you all, "my Family was watching TV but I'd be outside by myself..just thinking...how pitiful my life is.'".Now I want to tell you something, in that sentance it tells you it is your thoughts and only your thoughts are making you feel bad..trust me it is impossible to experience a negative feeling without first creating a corresponding negative thought.the actual source of our experience is always our thinking. So I would like you to try something that has worked for me, when you find yourself dwelling on something negative, anything that happened to you during the day, something that upset you and you want to churn it over and over, Stop, give it a few mins say 3 mins , time it, then say to your self "No more, I am fine, I feel alright,I am not thinking any more tonight," then go do something ,use control do not to let your thoughts wander , focus on something, ground yourself, distraction, anything chat to your Family , read a book it can be anything. If you get into the habit of doing this you will be able to do it easily,I conquered Panic attacks this way.If you fcus on the good things you have in your life you will always feeel better, write them down then see if you write down more good things than bad things. Feel better soon ,let us know ,we care..
