On my "hyper" days, I read, go to the gym, study at a cafe from day to night, and plan a shit ton of other things, On really bad episodes, I just sleep, eat, mindlessly consume media, and resume planning my CBT plan.
I wouldn't say anything I do to cope or distract make me feel better or "happy". Honestly, I've forgotten what true happiness feels like. Thoughts of hopelessness, hating myself, self-mutilating, CBT, and all that sort are always still there. Some days are just more intense than others.
The only thing that makes me feel somewhat at ease is hanging out with my friends. And it is also contingent on what I feel like at the time. Most of the time, I feel too ashamed of myself to go out. But I went to dinner with my friend yesterday. I was able to let myself loose and be temporarily distracted from the usually nagging feeling of emptiness and despair. I genuinely enjoyed our conversation. It made me realize how much I love her and remind me of the happy times we used to have together (something I consciously know but do not feel on a daily basis because I kinda feel numb towards affection nowadays)
Sitting behind her on her Vespa, and feeling the chilly wind hitting my face made me feel at peace for the first time in a long time. It is during these fleeting moments I think to myself maybe life is not so bad after all.
