I've been stressed and depressed a lot in the past two weeks, since then i dont get morning wood, could it be the reason?

Sex drive going: down because of depression is well-documented. Erectile potential decreases as anxiety increases, especially in perceived "demand" situations. However, even in depressed and anxious patients, erections are more likely to occur in the morning when male hormones are higher, and still occur in REM sleep. Check with a urologist to make sure nothing physical is going on, and then see a psych doc.
