So I am told by an energy that I am cursed in my previous life by Lakshmi because I raped her. This is little difficult for me to believe because I don’t see any such tendencies in me to rape any person. So those who are in touch with Lakshmi I request help to verify this.
There is a chance I feel it is a curse cause I have failed in everything until now education, career, lost good looks etc without any obvious reason. If anyone wants to help me regarding this It is appreciated.
You didn’t rape a Goddess, that’s ridiculous.
Cleanse and banish, sounds like a parasite trying to upset you. It picked the wrong guy that’s for sure, you know yourself. 
“Life’s a bitch and then you die” is the main reason, welcome to the club! 
We use magick to mitigate the slings and arrows of outrageous misfortune. It’s not necessary or helpful to blame everything that went wrong on the paranormal.
It’s possible that negativity in other lives created energy around you that attracts negativity in this one, but that can be cleared and healed. I say that because I pulled you a card and got “Fate Holder” implying this is connected to how your energy is configured, and your approach could be updated to work around this… I don’t believe in fate, but I do believe in "like attracts like’ and consequences.
if you have the senses open for it, I’d recommend evoking Lakshmi and asking her if she knows what’s going on. It’s your only lead, and you can’t trust randoms.
Then take each thing that failed as it’s own thing, analyze what happened and what you could have done differently, don’t lump them all in together, just work in improving your energy for those things and resolving each issue in it’s own right.
If it transpires that you did indeed harm someone like Lakshmi, connected to her, an aspect or avatar of her, then they’d start by feeling regret for your actions, apologizing to her for hurting her, knowing you’ll never do such a thing again, and forgiving yourself to move forward.
I would also ask Lakshmi herself and see if this is true.
