I know exactly what you mean. I've been on and off for years. At the moment I am pretty depressed due to some recent personal stuff that's happened to me. I just don't know how to be okay again, and I feel like I have no one to talk to. The people that do know what I've been through tell me I need to move on and move forward, but I don't know how. I feel so lost, empty and at times numb. Sometimes I just have to block out my thoughts to even get through the day without crying and I know I'm repressing a lot of my feelings atm, which will probably f**k me up even more long term, but it's the only strategy I have.
Then I have other factors affecting me at this point in time; such as missing home/family/friends and missing my job back home which I really enjoyed.
Gym is really the only outlet I have here. I do enjoy group fitness classes and I used to do boxing, which I loved, but my injuries make it difficult for me to be able to do those things, so I just stick to weights which I know I can do relatively pain free.
