im a female aged 21, and have had issues within my family for the past 5-6years. i have now lost all motivation, sex drive, and confidence with myself. generally a cant be bothered attitude. i have put on 4 1/2 stone in 2 years and when i do start to lose it, i lose all motivation again. i was wondering wether this was linked in any way with depression, as i feel like i always let down those around me.
