How do you deal with Anxiety and slight depression when in a relationship?

The kind that kills your sense of humor and lightheartedness. It really kills the DGAF mentality about things that normally slide right off you.

I have a hard time not believing she is starting to feel the effects of it and really tell that I'm not in the best place mentally.

She's been so damn good to me but between the anxiety and the gut feeling I have around her red flags I feel like I'm in a feedback loop from hell and losing sight of myself.

Red flags:

Partied hard + Sorority all through college.

Her Best friend cheats on her husband

In on anti-depressants and Adderall every day

Had no compass in her 20's. Did what she wanted, when she wanted. Says she never though about marriage and new the right guy would come along when the time was right.

was addicted to cocaine for 2 years

She gets irrationally upset around her parents. Does not respond well being around them and is very short tempered with them vs very sweet to me.

Says the last guy she was with cheated on her but she kept pictures of him on Instagram all summer. I saw an old msg to him and she started the msg "sorry to bother you, but do you still have that picture I gave you". That wasn't the type of behavior of someone who's actually been cheated on. Smells fishy.

Seems to be into hardcore bdsm in her young 20's and knows a fuck ton about tying people up.

All of this and she is the sweetest, kindest, loving girl I've ever been with.

She is either a master of telling me what need and want to hear/feel or actually in love with me."for now"
